ITEM 1.  BUSINESS

GENERAL DEVELOPMENT OF BUSINESS

          CalMat Co. (the "Company" or "Registrant") has its corporate
headquarters in Los Angeles, California and has operations throughout the state
of California, in Phoenix and Tucson, Arizona, and in Albuquerque, New Mexico.
The Company was formed in 1984 by the business combination of California
Portland Cement Company ("CPC") and Conrock Co. ("Conrock").  Following its
formation, the Company operated CPC as its Cement Division.  The Company
subsequently disposed of the Cement Division in an exchange transaction with
Onoda California, Inc. in 1990.  The Company's operations are primarily
concentrated in two business segments.  One of its business segments involves
the manufacture, production, distribution and sale of construction materials:
aggregates (crushed rock, sand and gravel), hot-mix asphalt and ready mixed
concrete.  This  business segment  experiences fluctuations with general levels
of activity in the construction industry and with weather-related construction
delays, which normally occur during the first and fourth quarters each year.  A
second  business segment is engaged in the ownership, leasing and management of
industrial and office buildings, the ownership and leasing of undeveloped real
property and sales of real property.

FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

          Information about the Company's business segments for the years ended
December 31, 1995, 1994 and 1993 is incorporated in Note 11 of the "Notes to
Consolidated Financial Statements," located on pages 28 and 29 of this Annual
Report on Form 10-K.

NARRATIVE DESCRIPTION OF BUSINESS

          CONSTRUCTION MATERIALS DIVISION

          The Construction Materials Division produces and sells construction
aggregates, hot-mix asphalt, and ready mixed concrete for use in commercial and
residential construction, public construction projects and projects to build,
expand and repair roads and highways.  The division operates aggregates
processing plants at 30 locations in the major markets of Southern and Central
California, the San Francisco Bay Area; Phoenix and Tucson, Arizona; and
Albuquerque, New Mexico.  The division also operates asphalt plants at 33
locations in the same markets as the aggregates processing plants, but in
addition, also operates in the Sacramento area.   Of the 33 hot-mix locations,
19 are sites which also have aggregates processing plants and/or ready mixed
concrete plants.  Ready mixed concrete batch plants are operated at 26 locations
in the same markets as the aggregates plants, except for the Los Angeles and San
Francisco Bay areas.  Of the 26 ready mixed concrete locations, 12 are sites
which also have aggregates processing plants.  Examples of projects to which the
Company will supply aggregates and/or ready mixed concrete in 1996 include:
Piers 302-305 at the Los Angeles Harbor in Los Angeles, California, the post-
earthquake rebuild of the Cypress freeway in Oakland, California destroyed by
the 1989 Loma Prieta earthquake, the Pleasanton/Dublin Bay Area Rapid Transit
extension in the San Francisco area, a waste water treatment plant in Fresno,
California, the widening of the 118 freeway lanes in Southern California's San
Fernando Valley, Phase III of the Red Line Tunnel in West Los Angeles, the
Arizona Museum of Science and Technology in Phoenix, Arizona, the Tucson,
Arizona  International Airport, the Cottonwood Mall in Albuquerque, New Mexico,
and the light rail transit line between downtown San Diego, California and Jack
Murphy Stadium.

          The Construction Materials Division was formed in 1995 as a
consolidation of the Company's former Concrete and Aggregates Division and its
Asphalt Division.  The former divisions were consolidated in order to streamline
the Company's operations, to eliminate redundancies, and to give customers a
single point of contact for the Company's

                                       1
<PAGE>
 
products.  Included within this new Division is Western Environmental
Contracting, Inc. (formerly known as Western Thermal Soils Company), a wholly
owned subsidiary that provides soil remediation, crushing and contracting
services.


          Aggregates
 
          Of the Company's 30 aggregates processing plants, 17 are located in
Southern California.  The Company believes it is the largest supplier of
construction aggregates in the greater Los Angeles area.  During 1995, the
Company sold 23.2 million tons of aggregates, representing less than half of the
Company's annual maximum production capacity. As of December 31, 1995, the
Company had estimated aggregates reserves of approximately 1.9 billion tons,
located near the major urban centers of the markets it serves.  A schedule of
the Company's estimated aggregates reserves is found on page 37 of this Annual
Report on Form 10-K.  The Company owns (or has long-term leases or options for)
all of the properties on which its reserves are located, and in all cases where
required by law the Company obtains permits from various governmental
authorities prior to the commencement of its mining activities.  Approximately
57% of the Company's total reserves are either fully permitted or in the process
of being permitted.  As is typical of major aggregates producers with a number
of production facilities, the currently permitted reserves at the Company's
quarries, expressed in terms of years of production at historical rates, varies
widely, in the Company's case from approximately two to three years at several
older facilities to in excess of 20 years at many others.  The Company has
permitting or alternative production plans to deal with all of its sites where
reserves could be depleted in less than 10 years, and believes that its current
reserves position provides it with a significant long-term competitive
advantage.

          To further assure sufficient reserves and adequate facilities to meet
future demand, the Company continues to add new aggregates reserves.  In early
1996, the Company acquired a 611-acre site in south San Diego County, which is
expected to yield 30 million tons of aggregates reserves.  During 1995, the
Company purchased its joint venture partner's 50% share of the partnership which
owns Azusa Rock, Inc., to become the sole owner of this 120-million ton reserve,
located ten miles from Los Angeles.  In March 1994 the Company was awarded a
contract to remove 18 million tons of rock, sand and silts from Irvine Lake in
Orange County, California where commercial aggregates production has recently
commenced.  In addition, the Company obtained permits for more than 50 million
tons of sand and gravel near San Bernardino, California in 1993 which should
allow the Company to meet its needs in that region for several decades.

          In December 1992 the Company acquired substantially all of the assets
of The Jamieson Company, a privately-held aggregates producer located in
Pleasanton, California.  This acquisition, which includes approximately 100
million tons of permitted reserves, enabled the Company to expand its aggregates
business into the growing San Francisco Bay Area and complemented the Company's
existing asphalt operations in that market.


          Hot-Mix Asphalt

          The Company's asphalt operations, under the trade name Industrial
Asphalt, represent the third largest supplier of hot-mix asphalt to the
construction industry nationwide, and the Company believes it is the largest
such supplier in California.  The Company produces and supplies asphalt and
related specialty products.  Unlike most of its competitors, the Company does
not undertake paving work, and thus does not compete with its customers, which
are principally contractors engaged in the paving business.

          The primary source of revenue from asphalt operations is from the sale
of hot-mix asphalt.  Hot-mix asphalt consists by volume of approximately 95%
aggregates and 5% liquid asphalt (a refined petroleum product).  Of the 33
Company locations with asphalt facilities, 19 are sites that also have
aggregates processing plants and/or ready mixed concrete plants.  This proximity
provides the Company with a competitive advantage in those markets due to the
availability of aggregates and transportation cost savings.  At all other
asphalt plants, more than one source of aggregates is available, and at all
asphalt plants, more than one source of liquid asphalt is available.

          In addition, the Company operates 13 asphalt recycling systems at its
major plants that recover aggregates and oil from asphalt that has been salvaged
from roads and other surfaces.  Used in the production of new asphalt paving,
the recovered aggregates and oil offer substantial cost savings, strengthen the
Company's ability to secure public projects, and provide a high return on
investment.  Two additional recycling systems are planned for 1996.

                                       2
<PAGE>
 
          During 1995, the Company acquired an asphalt plant located on the
Company's Carroll Canyon aggregates site, near San Diego, to enhance the
Company's responsiveness to local customers.  Also in late 1995, the Company
entered into a site lease agreement to erect an asphalt plant at Romoland in
Riverside County, California.

          The Company also manufactures related specialty products including
GUARDTOP(R), a seal coating material used for sealing asphalt pavement to
prevent water damage and surface erosion, and, under a license agreement, the
Company is the exclusive distributor in metropolitan Los Angeles of PETROMAT(R),
a polypropylene reinforcing fabric used in the resurfacing of pavement.  The
Company also maintains a fleet of paving machines and specialty paving equipment
which it rents, along with qualified operators, to contractors.
 

          Ready Mixed Concrete

          Ready mixed concrete, which consists by volume of approximately 80%
aggregates and 20% cement, water and other materials, is either delivered by the
Company's fleet of approximately 375 mixer trucks or by independent haulers. The
Company has vertically integrated into the ready mixed concrete business
primarily in those geographic areas where it has been necessary from a
competitive standpoint to provide an outlet for the Company's aggregates
production.


          PROPERTIES DIVISION

          The Properties Division manages the Company's extensive holdings of
over 32,000 owned and leased acres and is responsible for land acquisitions,
permitting, reclamation, sales and leasing activities.  Due to economies of
scale and the Company's experience and expertise in the permitting process, the
Company believes it has a significant advantage over most of its smaller
competitors in obtaining permits for its mining and other operations.  The
Company maintains substantial property holdings near the major urban centers of
the markets it serves and leases land containing aggregates reserves prior to
commencement of mining activities.  During 1995, approximately 130 leases
covering approximately 1,400 acres were in effect.  These leaseholds were used
for farming, storage locations and other uses.

          The Company's land management cycle includes acquiring property,
developing a master plan, obtaining land use entitlements, extracting
aggregates, and then reclaiming the mined property and preparing it for future
use.  The Company has generally been able to recycle previously mined properties
due in part to the efforts of its land management professionals.  The Company
reclaims land for a wide variety of uses such as agriculture, native habitat
restoration, water conservation and commercial, residential and industrial
development.  Reclaimed property may be subdivided into lots and sold to
developers after obtaining the necessary zoning and permits.

          As part of the Company's restructuring in 1988, the Company decided to
discontinue its business of developing industrial and office buildings.  Since
that time, the Company has sold 33 such buildings (totaling approximately 1.7
million square feet).  As market conditions permit, the Company intends to
dispose of its remaining commercial and industrial developments except for
certain industrial buildings which buffer the Company's mining and production
operations.  The Company currently owns over 0.9 million square feet of
commercial and industrial buildings, approximately 550,000 square feet of which
are located in close proximity to aggregates mining sites and buffer the
adjacent mining and processing operations.  The Division currently operates nine
landfills and expects to develop one additional landfill site in 1996.  All of
the Company's existing and planned landfills are designed and have permits to
accept only non-hazardous construction rubble.


          COMPETITIVE CONDITIONS

          The aggregates operations and the ready mixed concrete operations have
numerous competitors in each of their markets, but generally have fewer
competitors in the aggregates market than in the ready mixed concrete market.  A
majority of the ready mixed concrete business is obtained by competitive bid.
In addition to competitive pricing, the Company's other methods of meeting
competition include providing higher levels of service and higher quality
products to its customers.  Most of the Company's aggregates are delivered to
customers by third-party truckers.  The Company consumes a portion of its
aggregates production in the manufacturing of ready mixed concrete, and supplies
a portion

                                       3
<PAGE>
 
of its production to its asphalt operations for use in the production of hot-mix
asphalt.  Other sources of raw materials, such as cement used in ready mixed
concrete, are readily available.

          The Company's asphalt operations have more than one competitor in each
of its markets and have several competitors in most of its markets.  These
operators compete for business through price, quality and service to customers.

          In 1987, the Company entered into a ten-year consent decree with the
Justice Department limiting its ability to acquire additional asphalt operations
in the greater Los Angeles area, western San Diego County and other specified
areas of Southern California.  The 1995 acquisition of the Carroll Canyon
asphalt plant was completed with the consent of the Justice Department.



          REGULATIONS AND EMPLOYEES

          Regulations

          Substantial time and resources are expended by the Company to comply
with local, state and federal regulations for land use, health and safety, air
pollution and other environmental matters.  This is essential, because changes
in the enforcement of existing regulations or the addition of new laws and
regulations may require the Company to modify, supplement or replace equipment
or facilities.

          During the normal course of its operations, the Company uses and
disposes of materials, such as solvents and lubricants used in equipment
maintenance, which are classified as hazardous by some government agencies.  The
Company attempts to minimize the generation of such waste material and recycles
most of it.  A small amount of remaining wastes is disposed of in fully
permitted off-site landfills.

          Because of the nature of the Company's business, both the Occupational
Safety and Health Administration (OSHA) and the Mine Safety and Health
Administration (MSHA) have jurisdiction over its safety standards and controls.
Considerable effort is expended to train, inspect, report and enforce according
to OSHA and MSHA requirements.

          The Company continued to be successful in obtaining zoning approvals
and other required permits from local governing bodies allowing the mining of
aggregates and the conducting of the Company's other businesses.  The state,
county and city governing bodies within California, Arizona and New Mexico
continue to adopt new laws and regulations relating to land use.  Some of these
laws and regulations, including but not limited to the California Endangered
Species Act, may lead to attempts by special interest groups to reduce or
restrict the Company's use of its properties.


          Employees and Other Labor Information

          The Company had 1,671 full-time employees as of December 31, 1995.
Of these, 498 were salaried and 1,173 were hourly.

          The Company is party to 28 collective bargaining agreements covering
an aggregate of 959 employees.  Eight of these agreements, covering an aggregate
of 156 employees, are currently being negotiated, including one with its
Teamster employees in Albuquerque, New Mexico and three others with its Teamster
and Operating Engineer employees in Bakersfield, California.  If the Company is
unable to reach negotiated settlements for any of these contracts, it is likely
that a strike would occur.  A strike, should one occur, will depress volumes and
cause plant efficiencies to suffer.

          In July 1995, a labor strike by Southern California's I.U.O.E. Local
12 members, affecting 87 asphalt employees and 134 aggregates employees, caused
the Company to experience temporary volume losses and higher costs.  The strike
is still in effect but work is being performed by a combination of new employees
and returning workers.

          The Company is currently negotiating new contracts with several other
local unions (Teamsters, Laborers and Electricians) to succeed those which
expired in 1994 for its California locations in the counties of Los Angeles and

                                       4
<PAGE>
 
Orange, and in the cities of Fresno and Sanger, California.  In addition, the
Company has four other contracts relating to its asphalt employees that expire
in 1997; three with the Operating Engineers in its Fresno and Sacramento
locations, and one with the Operating Engineers in Phoenix.

          A labor agreement negotiated in 1993, which covers less than five
employees at the Company's Properties Division's landfill facilities, expires in
1996.


          OTHER

          In 1990 Onoda California, Inc., ("Onoda") and the Company consummated
a transaction whereby the Company distributed to Onoda all of its shares of
stock in California Portland Cement Company ("CPC") in exchange for certain
shares of stock of the Company that were then held by Onoda.  In addition, prior
to 1990, certain other related transactions were accomplished, including the
Company's contribution of certain assets to CPC and CPC's distribution of all of
its shares of stock in one of its subsidiaries to the Company (along with the
Company's distribution of the CPC stock to Onoda, the "Onoda Transactions").
The Onoda Transactions were reported as tax-free transactions for federal income
tax purposes.  Based on an analysis of the tax law in effect at the time of the
Onoda Transactions, the Company believes that this treatment of the Onoda
Transactions is correct, and has not established financial statement reserves
for this matter.  The Internal Revenue Service (the "IRS"), however, has yet to
examine the Onoda Transactions.  As a result, there can be no assurance that the
IRS will not challenge the Company's position regarding the proper tax treatment
of the Onoda Transactions.  If the IRS does challenge the Company's position and
is ultimately successful in denying the Company's treatment of the Onoda
Transactions, the resulting tax liability would have a material adverse effect
on the Company's financial position.

          As is the case with other companies in the same industries, the
Company's products contain varying amounts of crystalline silica, a common
mineral that is a component of most sands.  Excessive, prolonged inhalation of
very small particles (principally those less than ten microns in size) of
crystalline silica has been associated with non-malignant lung disease.  In
1987, the carcinogenic potential of crystalline silica was evaluated by the
International Agency for Research on Cancer and later by the National Toxicology
Program.  The International Agency found limited evidence of carcinogenicity in
humans but sufficient evidence of carcinogenicity in animals.  The National
Toxicology Program concluded in 1991 that crystalline silica is "reasonably
anticipated to be a carcinogen."  At present, the State of California does not
require warning notices concerning the carcinogenicity, if any, of crystalline
silica pursuant to California Proposition 65, but this policy is currently being
evaluated and is subject to change in the future.  In addition, future research
results could tend to implicate crystalline silica as a carcinogen or could fail
to show any association between crystalline silica and cancer.  The Company is
not a party to any litigation regarding crystalline silica.


ITEM 2.  PROPERTIES


PLANT FACILITIES

          See "Item 1. Business" on page 1 of this Annual Report on Form 10-K
for additional information relating to these properties.

          The Company makes a practice of leasing idle land which has been
obtained for its aggregates reserves during periods when the land is not used
for operations.  During 1995, approximately 130 leases covering more than 1,400
acres were in effect.  These leaseholds were used for farming, storage locations
and other uses.  Additionally, the Company owns approximately 0.9 million square
feet of commercial and industrial buildings, approximately 550,000 square feet
of which are located in close proximity to aggregates operations and buffer the
adjacent mining and processing operations.  A total of 32,678 acres are owned or
leased by the Company.

          See "CalMat Co., Property Owned and Leased" on page 36 of this Annual
Report on Form 10-K for additional information relating to these properties.

<PAGE>
 
ITEM 3.  LEGAL PROCEEDINGS

          The Company and its subsidiaries are involved in various lawsuits and
claims which the Company considers ordinary and routine in view of its size and
the nature of its business.  The Company does not believe that any ultimate
liability resulting from any such lawsuits will have a material adverse effect
on the operations or financial position of the Company.


ENVIRONMENTAL - GENERAL

          During the third quarter of 1992, the Company received a letter from
CPC, Onoda and Onoda U.S.A., purporting to assert a claim for indemnification
with respect to certain environmental matters, pursuant to certain provisions of
the agreement, dated July 19, 1988, under which Onoda acquired the stock of CPC.
The Company has notified these companies that it believes that it has no
liability with respect to the matters identified in the letter.  No dollar
amount of damages was specified, but the July 19, 1988, agreement limits any
potential liability with respect to such matters to a maximum of $16,000,000.


ENVIRONMENTAL - ADMINISTRATIVE AND JUDICIAL PROCEEDINGS

          Operating Industries, Inc. Landfill Site

          The U.S. Environmental Protection Agency ("EPA"), the State of
California and the California Hazardous Substance Account have named the Company
and over 200 other parties defendants in a civil action alleging joint and
several liability pursuant to certain California statutes and the Comprehensive
Environmental Response, Compensation and Liability Act ("CERCLA") in connection
with the cleanup of the former Operating Industries, Inc. landfill site in
Monterey Park, California.  The EPA alleges that the Company disposed of
hazardous substances representing 0.078 percent of the total volume of waste at
the site.  The Company believes, however, that the substances attributed to it
at the site were not hazardous.

          To date, the Company has contributed approximately $300,000 to fund
certain interim remedial actions at the site, as part of two partial settlements
of this matter (which in part remain subject to court approval). The EPA issued
a Remedial Investigation Report in October 1994.  A Feasibility Study, upon
which the final remedy will be based, is currently expected to be issued in late
1996.

          Because, among other things, the EPA has yet to select a final remedy
for the site and the Company's share of any liability is undetermined, the
ultimate outcome of this action cannot be predicted with certainty.  The Company
believes, however, that this matter will be resolved without a material adverse
effect on its financial position.  The Company's belief is based on its position
that the wastes attributed to it at the site were not hazardous, its extremely
small share of the waste at the site and the large number of other defendants,
and its belief that it has recourse to insurance coverage for at least a
substantial portion of any resulting liability.

          In a related development, the Company was among 150 defendants named
in a civil action filed in September 1994 in Los Angeles Superior Court by
approximately 100 individuals, alleging personal injuries and property damage
arising from the existence and operation of the Operating Industries landfill
site.  The complaint seeks "general, special and punitive" damages "according to
proof" at time of trial.  The Company contends that it has no liability in this
matter. However, the ultimate outcome of this action for the Company cannot be
predicted because the case is still in the preliminary stages of development,
there are a large number of parties alleged to be involved, the damages, if any,
will likely be apportioned between any defendants found to be responsible, and
there exists the potential for insurance coverage.

          San Gabriel Valley Superfund Area

          The EPA has named the Company and more than 300 other entities as
"potentially responsible parties" ("PRPs") under CERCLA in connection with
alleged groundwater contamination at four sites designated as San Gabriel Valley
Areas 1 to 4 in Los Angeles County, California (the "Sites").  The EPA has
advised the Company and the other PRPs that they may be jointly and severally
liable for releases of hazardous substances, not only from properties they owned
or operated, but also for area-wide groundwater contamination.  The Company's
corporate predecessor previously leased property the Company no longer owns to
Aerojet Electrosystem's corporate predecessor, which burned solid propellant
waste on the property.

          In January 1995 the Company received a letter from the EPA advising it
that the EPA does not plan to ask the Company to participate in the clean up of
the regional groundwater contamination.  Because no legal proceedings have been
initiated by the EPA and the investigation of the Sites is ongoing, the amount
that may ultimately be required for investigation and/or remediation with
respect to any contamination at the Sites or in the affected areas is presently
unknown and is unlikely to be determined for some time.  In addition, as a
result of uncertainty regarding the source and scope of contamination, the large
number of PRPs and the likelihood of varying degrees of responsibility among
various classes of PRPs, the Company's potential share of liability, if any,
cannot be determined at this time.

          San Fernando Valley Superfund Area

          The EPA has named the Company as a PRP under CERCLA in connection with
ongoing containment and remediation being conducted pursuant to an EPA Record of
Decision issued in 1987 for the San Fernando Valley Area 1 Superfund Site, North
Hollywood Operable Unit.  The EPA has advised the Company that, as an alleged
past owner of two properties and owner of a third property, all formerly
operated by other parties as landfills and alleged to be connected with the
contamination, the Company may be jointly and severally liable with at least
fifteen (15) other PRPs, including Allied-Signal, Inc., Lockheed Martin
Corporation and Waste Management Disposal Services of California, Inc., for
$17,213,355 in evaluation and containment costs incurred by the EPA.  The
current owners of the two properties which are no longer owned by the Company
have also been named as PRPs.

          Subsequently, the Company was named as a defendant in joint cost
recovery actions filed by the EPA and the California Department of Toxic
Substance Control in the United States District Court, Central District of
California. However, the Company has not been served with process, and, with
other PRPs, has entered into a Partial Consent Decree which, if approved by the
Court, would result in dismissal of the Company from the actions, at a cost
which would be less than the sum already reserved for this matter.  In the event
the Partial Consent Decree is not approved, the ultimate outcome of the action
cannot be predicted, because of, among other things, uncertainty regarding the
actual contributions to the contamination, if any, from the properties in
question, insurance coverage which may be available, the portion, if any, of
costs for which recovery is sought that could be allocated to the Company, and
the possibility of recovery from other PRPs or defendants or third parties not
named as PRPs or defendants.

     book value of certain developed real estate ($15.0 million).  Excluding

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

          This discussion should be read in connection with the consolidated 
financial statements.

RESULTS OF OPERATIONS

          Record rainfall and related flooding in the Company's California
markets early in the year and a labor strike which affected most of the Los
Angeles area construction materials operations had a pronounced negative impact
on 1995 results. Construction Materials Division earnings were lower than in
1994, due to decreases in aggregates and asphalt, partially offset by increases
in ready mixed concrete.  Properties Division earnings were also lower than in
1994, due to lower gains on sale of real estate, a decline in income from
developed properties caused by recent sales of such properties and a decrease in
income from landfill operations.

          The Company reported a net loss of $21.4 million, or $0.92 per share,
for 1995, which includes a non-cash charge of $26.5 million, or $1.14 per share,
to adopt Statement of Accounting Standards No. 121 "Accounting for the
Impairment of Long-Lived Assets and For Long-Lived Assets to be Disposed Of"
("SFAS 121"), and a charge of $1.2 million, or $0.05 per share, related to a
management consolidation within the Company's construction materials operations.
Excluding these special charges, net income would have been $6.3 million, or
$0.27 per share, compared with net income of $18.7 million, or $0.81 per share,
for 1994.

          Net income in 1994 was $18.7 million, or $0.81 per share, compared
with net income of $9.2 million, or $0.40 per share, for the year ended December
31, 1993.  Construction Materials Division earnings increased in 1994, due to
increases in asphalt, ready mixed concrete and soil remediation operations,
partially offset by decreases in aggregates.  The Properties Division earnings
for 1994 were sharply higher than 1993, largely due to increased gains on real
estate sales and higher income from landfill operations.

          Net income in 1993 of $9.2 million, or $0.40 per share, includes an
after-tax credit of $0.9 million, or $0.04 per share, resulting from the
adoption of the new accounting standard for accounting for income taxes and a
provision to income tax expense of $0.7 million, or $0.03 per share, to adjust
deferred taxes due primarily to the increase in the federal tax rate. Excluding
these items, earnings for 1993 would have been $9.0 million, or $0.39 per share.

CONSOLIDATED REVENUES AND EARNINGS

          Total revenues amounted to $378.2 million, $376.8 million and $353.5
million in 1995, 1994 and 1993, respectively. Included in total revenues are
gains from real estate sales of $4.1 million, $7.7 million and $2.1 million in
1995, 1994 and 1993, respectively.  Net sales and operating revenues, which
excludes gains on sale of real estate and other income, of $370.3 million in
1995 were up $5.1 million, or 1.4%, compared with $365.2 million in 1994. Net
sales and operating revenues were up $16.8 million, or 4.8%,  in 1994 compared
with 1993. Cost of goods sold as a percentage of net sales and operating
revenues was 88.2% in 1995 compared with 83.4% in 1994, mainly due to higher
average unit plant costs in the Construction Materials Division.  This
percentage was 85.0% in 1993.

          Interest expense decreased $1.8 million, or 40.6%, in 1995 compared
with 1994, due primarily to a decrease in the average borrrowings.  Interest
expense decreased 30.3% in 1994, compared with 1993, primarily because of lower
borrowings, partially offset by higher interest rates.

          Income (loss) before incomes taxes and cumulative effect of change in
accounting principle was ($36.9) million in 1995, versus $29.6 million in 1994.
The 1995 amount includes special charges of $47.0 million related to SFAS 121
($45.0 million) and costs related to a management consolidation within
construction materials operations ($2.0 million).  Excluding these special
charges, income was $10.1 million.  The decrease, excluding special charges,
consists of declines in earnings of the Construction Materials Division of $13.9
million, of which $3.3 million represents incremental out-of-pocket labor strike
costs incurred in 1995, and the Properties Division of $6.3 million, of which
$3.5 million was due to a decrease in gains on sales of real estate.  Income
(loss) before income taxes and cumulative effect of change in accounting
principle was $29.6 million in 1994, up from income of $14.9 million in 1993.
The increase in 1994 over 1993 consists primarily of improved earnings of the
Construction Materials Division and Properties Division of $4.9 million and $8.8
million, respectively.

                                       11
<PAGE>
 
          Selling, general and administrative expenses increased $1.3 million,
or 3.8%, in 1995 compared with 1994, which in turn increased $0.9 million, or
2.6%, from the 1993 level.

          The effective tax rate in 1995 was 42.0% compared with 36.7% in 1994
and 44.3% in 1993.  The 42.0% in 1995 is due primarily to the fact that the SFAS
121 charge was tax effected at 41.1%, the combined federal and state statutory
rate. Excluding the SFAS 121 charge, the effective tax rate in 1995 was 37.0%.
Excluding an adjustment to deferred taxes to account for the increase in the
federal tax rate, the effective tax rate in 1993 was 36.7%.

OPERATING DIVISIONS

          CONSTRUCTION MATERIALS DIVISION

          The Construction Materials Division produces and sells construction
aggregates, hot-mix asphalt, and ready mixed concrete for use in commercial and
residential construction, public construction projects and projects to build,
expand and repair roads and highways.  The division operates aggregates
processing plants at 30 locations in the major markets of Southern and Central
California, the San Francisco Bay Area; Phoenix and Tucson, Arizona; and
Albuquerque, New Mexico.  The division also operates asphalt plants at 33
locations in the same markets as the aggregates processing plants, but in
addition, also operates in the Sacramento area.   Of the 33 hot-mix locations,
19 are sites which also have aggregates processing plants and/or ready mixed
concrete plants.  Ready mixed concrete batch plants are operated at 26 locations
in the same markets as the aggregates plants, except for the Los Angeles and San
Francisco Bay areas.  Of the 26 ready mixed concrete locations, 12 are sites
which also have aggregates processing plants.

          As shown in the following table, 1995 aggregates and asphalt sales
volumes declined from 1994, mainly because of the record rainfall in California
in early 1995, as well as the labor strike in the Los Angeles area.  Volumes in
1994 decreased from 1993 as the slowdown in infrastructure work in California
more than offset increases from the January 1994 Los Angeles earthquake.

          Overall division revenue of $350.5 million was up 2.8% from 1994's
revenue of $340.8 million, which was up 4.3% from 1993's revenue of $326.9
million.  The increase in 1995's revenue was due to higher average sales prices
for ready mixed concrete and asphalt and higher volumes for ready mixed
concrete, which more than offset lower volumes for aggregates and asphalt.  The
increase in 1994's revenues resulted from higher average sales prices for
aggregates, ready mixed concrete and asphalt and higher volumes for ready mixed
concrete, partially offset by lower volumes for aggregates and asphalt.  Also
contributing to the higher revenue was increased revenue from soil remediation
operations.

          In 1995, the average sales price of aggregates was virtually unchanged
from 1994.  Gross profit for aggregates, excluding incremental out-of-pocket
strike costs, decreased $4.4 million due to the combination of a 6% volume
decline and 5% higher unit production costs.  Asphalt gross profit, excluding
incremental out-of-pocket strike costs, declined by $4.9 million due to the
combination of a 2% volume decline and 8% higher unit production costs,
partially offset by a 3% increase in average sales price.  More than one-half of
the cost increase was due to the increased costs of liquid asphalt and
aggregates.  Gross profit from ready mixed concrete sales increased $1.8 million
due to a 15% increase in unit sales volumes and a 2% increase in average sales
price, partially offset by 2% higher unit production costs.  Ready mixed
concrete operations were not as negatively impacted by the heavy rainfall in
California early in the year, because a much larger percentage of the Company's
ready mixed concrete business is in Arizona and New Mexico, where weather
conditions were less adverse.  Income from soil remediation operations declined
$2.0 million from 1994 levels due to a substantial reduction in volumes
processed.

                                       12
<PAGE>
 
          In 1994, the average sales price of aggregates increased 5.7% compared
with 1993.  Gross profit for aggregates during 1994 decreased $1.3 million as
higher unit production costs and a 3.2% volume decline more than offset the
increase in average sales price.  Gross profit for asphalt increased by $3.8
million in 1994 as a result of a 3.4% increase in average sales price and a $2.2
million increase in income from soil remediation operations offset partially by
slightly higher unit production costs and a 3.7% volume decline.  Gross profit
for ready mixed concrete increased by $3.8 million in 1994 as a 7.4% increase in
average sales price and a 7.0% increase in unit sales volume more than offset a
3.4% increase in unit production costs.

          Selling, general and administrative expenses increased 1.7% in 1995
from the 1994 level, which in turn had increased 0.7% from 1993.  Income from
operations decreased to $10.3 million in 1995 from $24.2 million in 1994 which
had increased from 1993's level of $19.3 million.

          PROPERTIES DIVISION

          The Properties Division manages the Company's real estate and is
responsible for acquisitions, permitting, reclamation, sales and leasing
activities.

          Income from operations was $11.2 million in 1995 compared with $17.6
million in 1994.  Included in 1995 are gains from real estate sales of $4.1
million versus gains of $7.7 million in 1994.  Excluding real estate gains,
Properties Division income from operations decreased $2.8 million.  The decrease
was due to a $1.2 million decline in income from developed properties due to
recent sales of such properties, and a $0.9 million decrease in income from
landfill operations due, in part, to the adverse weather in California in early
1995 and an unusually large contract in Arizona in 1994.

ENVIRONMENTAL MATTERS

          The Company is subject to federal, state and local environmental laws
and regulations which require the Company to remove or mitigate the effect on
the environment of the disposal or release of certain chemical, mineral and
petroleum substances at various sites.  Generally, the Company's exposure has
been limited to soil contamination from underground fuel tanks or fuel spillage
rather than exposure resulting from generation of hazardous waste, although it
is a "named party" or "potentially responsible party" at three federal Superfund
sites.

          The Company conducts annual environmental assessments of each of its
operating sites.  Liabilities are recorded when environmental assessments and/or
remedial efforts are probable, and the costs can be reasonably estimated.
Generally, the timing of these accruals coincides with completion of a
feasibility study or the Company's commitment to a formal plan of action. As
investigation or remediation proceeds, and as the scope of the Company's
obligations become more clearly defined, there may be changes to estimated
costs, which might result in future charges to earnings.

          During 1995, the Company charged to income $2.3 million before tax for
environmental remediation costs and made related payments of $0.2 million.  At
December 31, 1995, the reserve for environmental remediation costs totaled $5.4
million. The amount reserved represents the estimated undiscounted costs which
the Company will incur to remediate sites with known contamination.  No
potential insurance recoveries have been offset against the reserve.
Substantially all amounts accrued in the reserve are expected to be paid out
over the next five years.

OTHER

          Previous mention has been made of the negative impact the labor
strike, which affected most of the Los Angeles area construction materials
operations, had on 1995 results.  Although the labor strike is still in effect,
the Company has replaced all necessary positions, and plant operations and
business levels are returning to their pre-strike norms.

          During 1995, the Company revised its inventory valuation process for
income tax purposes.  In order to conform its book inventory valuation process
more closely to this change, the Company recorded a cumulative increase in
inventories of $5.4 million at December 31, 1995.

          In connection with the operating property valuation process undertaken
in the adoption of SFAS 121, the Company also reassessed its reclamation
provision policies and concluded it appropriate to increase its reclamation
reserve.  During 1995, the Company charged to income $7.8 million before tax for
reclamation costs and made related payments of $1.2 million.  The

                                       13
<PAGE>
 
Company expects future annual charges for reclamation obligations to approximate
the average charge for the years 1993, 1994 and 1995 (exclusive of the charge
related to the reassessment), which was $2.7 million.  At December 31, 1995, the
reserve for reclamation obligations totaled $11.6 million.

LIQUIDITY AND CAPITAL RESOURCES

          CASH FLOWS

          Cash and cash equivalents decreased $2.1 million in 1995, which in
turn decreased $8.5 million from 1993.

          Operating activities are the principal source of CalMat's cash flows.
Over the past three years, operating activities have provided $131.7 million in
cash.  Net cash of $43.8 million generated from operating activities in 1995 was
essentially unchanged from 1994 and 1993, which were $44.0 million and $43.9
million, respectively.

          Cash used for investing activities totaled $53.6 million in 1995, a
$51.9 million increase from the 1994 level.  The primary reasons for this change
were increased spending on property, plant and equipment of $31.1 million, the
acquisition of the remainder of a business previously partially owned for $11.7
million, and increases in installment notes receivable of $6.9 million.  Cash
used for investing activities totaled $1.7 million in 1994, a $2.6 million
decrease from the 1993 level. The primary reasons for this change were increased
proceeds from sales of real estate of $17.8 million offset by increased spending
on property, plant and equipment of $13.8 million.

          Net cash provided by financing activities amounted to $7.6 million in
1995, a $58.4 million change from the $50.8 million used for financing
activities during 1994.  The primary reason for this change was $15.8 million in
net increase in notes payable to banks in 1995 compared with $42.5 million in
net payments on notes payable to banks and notes and bonds payable in 1994. Net
cash used for financing activities amounted to $50.8 million in 1994, a $21.8
million change from the $29.0 million used for financing activities during 1993.
The primary reason for this change was $25.8 million more in net payments on
notes and bonds payable in 1994 compared with 1993.

          Capital expenditures increased in 1995 to $57.0 million from $25.8
million in 1994, which was largely due to expansion projects, including the
construction of mining and processing facilities located at Irvine Lake in
Orange County, California, two new asphalt plants in Southern California and a
portable aggregates crushing plant.  Management believes that cash provided by
operations and existing borrowing arrangements will provide adequate funds for
current commitments and expected working capital requirements during 1996.

          During both 1995 and 1994, the Company expended $9.3 million in cash
dividends.

          WORKING CAPITAL

          Working capital totaled $33.6 million at December 31, 1995, a $1.3
million decrease from the 1994 total of $34.9 million, which was $4.0 million
less than the 1993 level of $38.9 million.  This decrease was due to the $8.5
million decrease in cash and cash equivalents.

          OTHER

          Total consolidated long-term and short-term borrowings at December 31,
1995 of $84.4 million increased $15.6 million from the balance at December 31,
1994 of $68.8 million, which had decreased $46.7 million from the balance at
December 31, 1993 of $115.5 million. The decrease in debt in 1994 was paid from
cash flows from operations.  Debt as a percent of total capitalization was 20.3%
and 16.0%, at December 31, 1995 and 1994, respectively.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To the Stockholders and Board of Directors
CalMat Co.
Los Angeles, California

    We have audited the accompanying consolidated balance sheets of CalMat Co.
and subsidiaries as of December 31, 1995 and 1994, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended December 31, 1995, and the related financial
statement schedule as listed in the index on page 15 of this Annual Report on
Form 10-K. These consolidated financial statements and the financial statement
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these consolidated financial statements and the
financial statement schedule based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements.  An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation.  We believe that our audits
provide a reasonable basis for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
CalMat Co. and subsidiaries as of December 31, 1995 and 1994, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995, in conformity with generally
accepted accounting principles.  In addition, in our opinion, the financial
statement schedule referred to above, when considered in relation to the basic
financial statements taken as a whole, presents fairly, in all material
respects, the information required to be included therein.

    As discussed in Note 3 to the consolidated financial statements, effective
January 1, 1993, the Company changed its method of accounting for income taxes.

where ownership is between 20 and 50 percent.

CASH AND CASH EQUIVALENTS:   Cash and cash equivalents include all cash balances
and highly liquid investments with a maturity of three months or less when
purchased.

INVENTORIES: Inventories are recorded when purchased or produced and are stated
at the lower of cost or market.  The Company revised its inventory valuation
process for income tax purposes and has adopted similar methodology for book
purposes.  The annual impact for book and tax purposes is not expected to be
material.

COSTS IN EXCESS OF NET ASSETS OF BUSINESSES ACQUIRED:   Costs in excess of the
fair value of net assets of businesses acquired are amortized on a straight-line
basis over periods not exceeding 40 years. Accumulated amortization of such
costs was $11.1 million and $9.4 million at December 31, 1995 and 1994,
respectively.  The Company periodically assesses whether there has been a
permanent impairment in the value of goodwill and other intangible assets by
considering factors such as expected future operating income, current operating
results, trends and prospects, as well as the effects of demand, competition,
and other economic factors.  Management believes no impairment has occurred.

PROPERTY, PLANT AND EQUIPMENT:   Property, plant and equipment is carried at
cost.  Depreciation is computed using primarily straight-line rates over
estimated useful lives (5 to 35 years for plant structures and components and 4
to 25 years for machinery and equipment).

          Depletion of rock and sand deposits is computed by the unit-of-
production method based upon estimated recoverable quantities of rock and sand.

          Significant expenditures which add materially to the utility or useful
lives of property, plant and equipment are capitalized. All other maintenance
and repair costs are charged to current operations.

          The cost and related accumulated depreciation of assets replaced,
retired or otherwise disposed of are eliminated from the property accounts, and
any gain or loss is reflected in income.

RECLAMATION COSTS: The estimated costs of reclamation associated with mining
activities are accrued during production and classified as long-term
liabilities.  Such costs are taken into account in determining the cost of
production.  The reserve for reclamation costs was $11.6 million and $5.0
million at December 31, 1995 and December 31, 1994, respectively.

ENVIRONMENTAL:   Environmental remediation expenditures that relate to current
operations are expensed or capitalized as appropriate. Expenditures that relate
to an existing condition caused by past operations, and which do not contribute
to current or future revenue generation, are expensed.  Liabilities are recorded
when environmental assessments and/or remedial efforts are probable, and the
costs can be reasonably estimated. Estimated liabilities are not discounted to
present value. Generally, the timing of these accruals coincides with completion
of a feasibility study or the Company's commitment to a formal plan of action.
The reserve for environmental remediation costs was $5.4 million and $3.2
million at December 31, 1995 and December 31, 1994, respectively.

SELF-INSURANCE:   The Company is self-insured up to certain levels for workers'
compensation, automobile liability and general liability. The Company is also
self-insured for health care claims for eligible active and retired employees.
The Company accrues its estimated costs monthly in connection with its portion
of insurance losses/claims. Claims paid by the Company are charged against the
reserve. Additionally, the Company maintains a reserve for claims incurred but
not reported based on actuarially estimated costs.

ACCOUNTING ESTIMATES: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period.  Actual results could differ from those estimates.

REVENUE RECOGNITION:   Sales and operating revenues are recorded upon shipment
of product, net of discounts, if any, and include revenue earned pursuant to the
terms of property leasing contracts.  Gains and losses on real estate are
recorded upon consummation of the transaction.  Other income relates primarily
to interest and dividend income, miscellaneous rental income and gains on sale
of fixed assets which are recognized in accordance with the terms of various
contractual arrangements or upon receipt (as applicable).

RECLASSIFICATION: Certain prior year amounts have been reclassified to conform
with the current year's presentation.

          In January 1993, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes."  The adjustments to the
January 1, 1993 balance sheet to adopt SFAS 109 netted to a credit of $0.9
million. This amount was reflected in 1993 net income as the cumulative effect
of a change in accounting principle.

          At December 31, 1995, the Company had alternative minimum tax credit
carryforwards of approximately $2.2 million available to offset regular tax in
future years.

          The Company's federal consolidated income tax returns have been
examined and settlements have been reached for all years through 1989, except
for certain assessments made for the years 1986 and 1987, which are presently
being negotiated at the appellate level. The Company believes that adequate
provision has been made for possible assessments of additional taxes.

          At December 31, 1995, the Company had a formal committed revolving
credit facility with a group of banks totaling $125.0 million which will expire
in 1998.  The Company pays a facility fee on the committed facility.

          Short-term bank borrowings made under this credit facility and
included in notes payable to banks were $48.0 million and $32.3 million at
December 31, 1995 and 1994, respectively, and bore rates equal to or less than
the prime bank lending rate which was 8.5% at December 31, 1995 and 1994.
Committed credit available under the revolving credit facility provides
management with the ability to refinance the short-term bank borrowings on a
long-term basis and, as it is management's intention to do so, these borrowings
have been classified as long-term debt.

          The senior notes bear interest at 6.7% and require principal payments
beginning in 1997 through 2000.

          The credit agreements contain restrictions with respect to the
incurring of additional debt, creation of liens and guarantees, and maintenance
of minimum net worth and financial ratios.

          Maturities of notes and bonds payable during the next five years are
as follows: 1996, $0.1 million; 1997, $8.8 million; 1998, $56.8 million; 1999,
$8.8 million; and 2000, $8.9 million.


NOTE 5:  STOCK OPTIONS AND RIGHTS

          The Company has stock option plans that provide for granting incentive
and non-qualified options on common stock to officers, directors and key
employees. During 1993, the Board of Directors adopted the 1993 Stock Option
Plan for Executive and Key Employees of CalMat Co. which authorized the issuance
of options covering 900,000 shares of common stock. Certain information relative
to stock options follows:

grant. Options generally become exercisable in four annual installments
beginning one year after the date of grant and expire ten years after the grant
date.  No options expired in 1995 and 1993.  In 1994, 220 options expired.  In
January 1996, options to purchase a total of 237,000 shares of common stock were
granted to officers and key employees.

          In September 1987, the Company declared a dividend distribution of one
common share purchase right on each outstanding share of common stock. When
exercisable, each right will entitle its holder to buy one share of the
Company's stock at a price of $90 per share until September 1997. The rights
will become exercisable if a person acquires 25.0% or more of the Company's
stock or makes an offer, the consummation of which will result in the person's
owning 30.0% or more of the Company's stock. In the event the Company is
acquired in a merger, each right entitles the holder to purchase common stock of
the surviving company having a market value twice the exercise price of the
right. The rights may be redeemed by the Company at a price of $.05 per right at
any time prior to a person acquiring 25.0% of the Company's common stock.


NOTE 6: EARNINGS PER SHARE

          Earnings per common equivalent share (common shares adjusted for
dilutive effect of common stock options) have been computed by dividing net
income for each period by the weighted-average shares of common stock
outstanding.

          Weighted-average shares used for 1995, 1994 and 1993 totaled
23,176,000, 23,224,000 and 23,117,000, respectively.


NOTE 7:  FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK

          The Company has only limited involvement with derivative financial
instruments and does not use them for trading purposes. The Company enters into
interest rate swap agreements to manage its interest rate risk. Interest rate
swaps allow the Company to effectively convert a portion of its floating-rate
borrowings into fixed-rate obligations. The interest rate differential to be
received or paid is recognized over the lives of the agreements as an adjustment
to interest expense. Counterparties to these agreements are high credit quality
financial institutions, and nonperformance is considered remote. In the unlikely
event that a counterparty fails to meet the terms of an agreement, the Company's
exposure is limited to the interest rate differential.

          The Company had outstanding interest rate swap agreements that
effectively converted $15.0 million in 1995 and $25.0 million in 1994 of
variable rate debt to fixed rate borrowings at December 31, 1995 and 1994,
respectively.  These agreements expire in 1996.

          Financial instruments which potentially subject the Company to
concentrations of credit risk consist principally of periodic temporary
investments of excess cash and trade receivables. The Company places its
temporary excess cash investments in high quality short-term money market
instruments through several high credit quality financial institutions. At
times, such investments may be in excess of the FDIC insurance limit. A
significant portion of the Company's sales are to customers in the construction
industry, and, as such, the Company is directly affected by the well-being of
that industry. However, the credit risk associated with trade receivables is
minimal due to the Company's large customer base and ongoing control procedures
which monitor the credit worthiness of customers.  The Company generally obtains
lien rights on all major projects.  Historically, the Company has not
experienced significant losses on trade receivables.

          The following disclosure of the estimated fair value of financial
instruments is made in accordance with the requirements of Statement of
Accounting Financial Standards (SFAS) No. 107, "Disclosures About Fair Value of
Financial Instruments." The estimated fair value amounts have been determined by
the Company using available market information and valuation methodologies
described below. However, considerable judgements are required in interpreting
market data to develop the estimates of fair value. Accordingly, the estimates
presented herein may not be indicative of the amounts that the Company could
realize among willing parties in a current market transaction.

          The carrying values of cash equivalents, trade receivables and
accounts payable approximate fair values due to the short-term maturities of
these instruments. The carrying amounts and estimated fair values of the
Company's other financial instruments at December 31 are as follows:

</TABLE>

The methods and assumptions used to estimate the fair value of each class of
financial instruments are as follows:

NOTES RECEIVABLE: The fair value has been estimated using the expected future
cash flows discounted at market interest rates.

NOTES AND BONDS PAYABLE: The fair value was estimated by discounting the future
cash flows using rates currently available for debt of similar terms and
maturity. The carrying values of short-term bank loans were assumed to
approximate fair values due to their short-term maturities.

INTEREST RATE SWAPS: Fair values are based on market value estimates from
dealers.


NOTE 8:  RETIREMENT PLANS

          The Company has a trusteed thrift and profit-sharing retirement plan
and a money purchase pension plan to provide funds from which retirement
benefits are paid to substantially all salaried employees of the Company and its
wholly owned subsidiaries, including officers and directors who are also
employees. Annual contributions to these plans made by the Company approximate
15.0% of the aggregate compensation paid or accrued each year to participants in
the plan. The Company also contributes to various union pension plans, as
specified by certain union agreements, and non-union pension plans which cover
substantially all hourly employees. Contributions to all retirement plans
charged to income totaled $7.9 million in 1995, $8.2 million in 1994 and $8.0
million in 1993.

          The Company provides certain health care and life insurance benefits
to eligible retired employees. Salaried and non-union hourly participants
generally become eligible after reaching age 62 with 20 years of service or
after reaching age 65 with 15 years of service. The health care plan is
contributory and the life insurance plan is noncontributory. The plans are
unfunded.

          The following table sets fort the plans' funded status reconciled with
the amount included in the caption other liabilities and deferred credits in the
Company's balance sheets at December 31:

</TABLE>

          For measurement purposes, an 11.3% annual rate of increase in the per
capita cost of covered health care benefits was assumed for 1996; the rate was
assumed to decrease gradually to 6.0% by 2011 and remain at that level
thereafter. The weighted-average discount rate used in determining the
Accumulated Postretirement Benefit Obligation was 7.0% in 1995, 8.0% in 1994 and
7.0% in 1993.

          The health care cost trend rate assumption has a significant effect on
the amounts reported. To illustrate, increasing the assumed health care cost
trend rates by one percentage point in each year would increase the Accumulated
Postretirement Benefit Obligation as of December 31, 1995 by $1.0 million and
the aggregate of the service and interest cost components of net periodic
postretirement benefit cost for the year then ended by $0.1 million.


NOTE 9: SPECIAL CHARGES

          The Company recorded a special charge of $2.0 million in the second
quarter of 1995 relating to the consolidation of the Company's construction
materials operations.  The net after-tax effect of this charge was $1.2 million,
or $0.05 per share.

          The Company adopted Statement of Financial Accounting Standards No.
121, "Accounting for the Impairment of Long-Lived Assets and For Long-Lived
Assets to be Disposed Of " ("SFAS 121") during the fourth quarter of 1995.  This
required accounting change resulted in a pre-tax charge of $45.0 million ($26.5
million after-tax, or $1.14 per share).

          SFAS 121 changes the method of determining and measuring impairment
for long-lived assets.  For operating properties, the new standard requires that
impairment be measured at the plant or specific property level; under previous
accounting rules it was acceptable to measure impairment at the regional or
divisional level.  Further, if an impairment, as now defined, is identified, the
new standard requires measurement of the impairment using fair value, which in
most cases requires the use of discounted cash flows, which is the principal
reason for the write-down of real estate development projects.  Given the nature
of the Company's assets, the new requirements resulted in substantially greater
write-downs than under previous accounting rules.

     The $45.0 million pre-tax charge can be broken out as follows:

<TABLE>
 
<S>                                   <C>
Operating properties                   $24,648
Real estate development projects        14,821
Assets to be Disposed Of                 5,531
                                       -------

                                       =======
</TABLE>

          Impairment charges for operating properties relate to sites where, due
to intense competition and/or difficult production environments, marginally
profitable or loss operations persist.  Impairment charges for real estate,
including Assets to be Disposed Of, stem from severe declines in California and
Arizona real estate values for properties acquired or development projects
committed to at the peak of those markets.  The Company anticipates the sale of
Assets to be Disposed Of during 1996. The carrying value of Assets to be
Disposed Of aggregated $11.9 million at December 31, 1995.

NOTE 10:  COMMITMENTS AND CONTINGENCIES

          The Company had letters of credit outstanding totaling approximately
$36.0 million at December 31, 1995, which guarantee various insurance and
financing activities.

          The Company has retained certain self-insurance risks with respect to
losses for workers' compensation, automobile and general liability and certain
health care claims.

          The Company has been named by the U.S. Environmental Protection Agency
("EPA") as a defendant in a civil action involving one "Superfund" cleanup site
and as a "potentially responsible party" ("PRP") with respect to two other such
sites. In each instance the Company is one of many entities so named. Because,
in the case of the site involved in ongoing litigation, no final remedy has been
selected, and with respect to the other two sites, investigation is ongoing, the
Company's share of total liability, if any, is unable to be quantified at this
time. In the case of the site involved in ongoing litigation, the Company
believes that the wastes attributed to it were not hazardous. In addition, the
waste attributed to the Company represents an extremely small (less than one
tenth of one percent) percentage of the total volume of waste at this site.

          The Company is subject to various legal proceedings, claims and
liabilities which arise in the ordinary course of its business. In the opinion
of management, the amount of ultimate liability with respect to these actions
will not have a material adverse effect on the Company's results of operations,
cash flow or financial position.


NOTE 11:  BUSINESS SEGMENT INFORMATION

          The Company operates principally in two business segments:
Construction Materials and Properties.  Operations in the Construction Materials
Division include the mining and sale of aggregates (rock, sand and gravel), the
manufacture and sale of ready mixed concrete, and the manufacture and sale of
hot-mix asphalt.  The division maintains a fleet of specialty paving equipment
which it rents to customers.  It also markets Guardtop(R), an asphalt surface
sealer, and is a distributor of paving reinforcement fabric.  Also included in
this division is Western Environmental Contracting, Inc. (formerly known as
Western Thermal Soils), a wholly owned subsidiary that provides soil
remediation, crushing and contracting services.  These products and services are

and San Francisco Bay areas of California; Phoenix and Tucson, Arizona; and
Albuquerque, New Mexico.  Ready mixed concrete batch plants are operated at 26
locations in these markets except for the Los Angeles and San Francisco Bay
areas.  Of the 26 ready mixed concrete locations, 12 are sites which also have
aggregates processing plants. Asphalt plants are operated at 33 locations in
metropolitan Los Angeles and San Diego, the San Francisco Bay and San Joaquin
Valley areas of California; Phoenix and Tucson, Arizona; and Albuquerque, New
Mexico.  Of the 33 asphalt plant locations, 19 are sites which also have
aggregates processing plants and/or ready mixed concrete plants.

          The Properties Division manages the Company's real estate and is
responsible for acquisition, permitting, reclamation, sales and leasing
activities.  These activities take place principally in Los Angeles and San
Diego, California and Phoenix, Arizona.

          Income (loss) from operations by segment represents total revenues
less direct operating expenses, segment selling, general and administrative
expenses and certain allocated corporate general and administrative expenses.
Corporate and unallocated expenses include corporate administrative expenses and
support expenses not allocated to business segments.  Assets classified as
corporate and other consist primarily of cash and cash equivalents, notes
receivable, general office facilities and other assets.

          A substantial portion of the Company's revenues and income before
taxes result from construction materials operations located in Southern
California.

(these are the only changes).
 
     Please review the two changed pages to the Second Amendment, and if they
are acceptable to you, please sign this letter below acknowledging your approval
and return a copy of your signature on this letter via facsimile to the

     This is a restatement of an amended and restated Employment Agreement
     ("Agreement") originally effective as of July 1, 1984, and most recently

     B.  The Company desires to provide for the Executive's compensation
     commensurate with the position of Chairman of the Board, President, Chief

                                   AGREEMENT
                                   ---------

     such position, the Executive shall have at least such responsibilities and
<PAGE>
 
                                                                               2

     Company in effect on the date hereof.  During his employment hereunder, the
     Executive shall devote his full energies, interest, abilities and
     productive time during normal business hours to the performance of this
     Agreement and shall, without the Company's prior written consent in each
     instance, refrain from rendering services of any kind to others for
     compensation or which would materially interfere with the performance of
     his duties under this Agreement.  Notwithstanding the foregoing, the
     Executive may serve as a director of other companies with the consent of
     the Company's Board of Directors.

     Section 1.2:  TERM OF EMPLOYMENT

               (b) During such term of this Agreement, the Executive's
     employment shall not be subject to termination at the instance of the
     Company for cause or for any other reason and the Executive's compensation
     and other benefits as provided herein shall continue unabated during the
     full term of this Agreement and otherwise as provided herein; provided,
     however, that the Board of Directors of the Company shall have the right,
     acting in accordance with the  By-laws of the Company, to remove the
     Executive from office as Chairman of the Board, President, Chief Executive
     Officer and Chief Operating Officer of the Company in the event the
     Executive acts in any way which has a direct, substantial and adverse
     effect upon the reputation or condition of the Company, in which event the
     Executive may terminate his employment pursuant to Section 1.5.

     Section 1.3:  TERMINATION OF AGREEMENT UPON DISABILITY OF

               If at the end of any calendar month, the Executive is and has,

                                                                               3

                    EXECUTIVE
                    ---------

               If the Executive dies, this Agreement shall be terminated on the
     last day of the calendar month of his death.

     Section 1.5:  TERMINATION OF EMPLOYMENT BY THE EXECUTIVE
                   ------------------------------------------

               If, without the Executive's express written consent, the Company
     (i) significantly reduces the importance of the functions, duties,
     responsibilities or authority of the Executive, (ii) reduces the
     Executive's compensation or benefits, or (iii) relocates the principal
     executive office of the Company to a location outside of Los Angeles County
     or reassigns the Executive to a location other than the principal executive
     office of the Company (except for required travel on the Company's business
     to an extent substantially consistent with the Executive's travel
     obligations existing on the date of this Agreement), then the Executive may
     inform the Company that such action by the Company constitutes constructive
     notification under Section 1.2 that this Agreement will be terminated four
     years thereafter. Executive shall continue to receive compensation during
     the notice period. Notwithstanding the notice provision contained in
     Section 1.2(a), after any such constructive notice or actual notice to the
     Executive of the termination of this Agreement by the Company pursuant to
     Section 1.2, the Executive may at any time terminate his employment with
     the Company. In the event of such a termination of employment by the
     Executive, the Company shall within 72 hours make a payment to the
     Executive of the lump-sum value (without any present-value discount or
     adjustment for inflation) of the salary and benefits that would have been
     provided to the Executive for the period from the date of such resignation

     adjustment pursuant to Section 3.3) and to provide him with benefits as

     Section 3.2:  PARTICIPATION IN OTHER COMPANY BENEFITS
                   ---------------------------------------

               In addition to the benefits provided in this Agreement, the
     Executive shall, throughout the term hereof (prior to death), be entitled
     to and shall receive all other benefits generally available to other
     executives of the Company, including (without limitation) benefits under
     the Company's medical, health, disability, death benefit, profit sharing
     and bonus and other incentive compensation plans (other than stock option
     plans).  The Executive shall be entitled to receive benefits which are at
     least as great in scope and amount as those received by any other employee
     of the Company. The Executive shall also be entitled to benefits under the
     Company's Supplemental Executive Retirement Plan ("SERP"), whether or not
     the SERP is available to other executives. If the Executive's employment is
     terminated pursuant to Section 1.2(b), Section 1.3 or Section 1.5: (i) the
     amount the Executive otherwise would have received as bonus payments for
     the period after the termination shall be determined assuming that he would
     be entitled to an annual bonus or bonuses at an annual rate at least equal
     to the average of his annual bonuses for the preceding two years and that
     he would be entitled to receive a pro-rata portion of such amount for any
     period shorter than a full calendar year; (ii) the amount of the profit
     sharing plan contributions otherwise made on behalf of the Executive shall
     be determined assuming that the level of Company contributions to the plan
     would equal the average of such levels for the preceding two years; (iii)
     the payment for the value of welfare benefits shall be based on the current
     cost of such coverage to the Company and shall take into account the
     Executive's entitlement to participate in the Company's welfare benefit
     plans for retirees (if he would have qualified for such participation
     assuming he had an additional four years of service); (iv) the Executive
     shall continue to have use of an automobile as provided in Section 2.2
     (until the end of the appropriate four-year period under Section 1.2(b),
     Section 1.3 or 1.5, as the case may be) unless and until he elects during
     such period to purchase the car from the Company at a price equal to the
     greater of its book value to the Company or its wholesale selling price;
     and (v) the amount to which the Executive would otherwise be entitled under
     the SERP shall be determined (A) based on his age at the date he would
     otherwise have terminated employment, (B) taking into account the salary he
     would have earned through such date based on his salary rate in effect at
     his actual termination date increased using the 6.5% salary

     Section 3.3:  COST OF LIVING ADJUSTMENT
                   -------------------------

               The bi-weekly or semi-monthly payments to be paid to or on
     account of the Executive in any year under Section 3.1 shall be increased
on January 1 of each year after January 1, 1984 (the "adjustment date"), in the
same proportion as the proportional difference between the "Consumer Price Index
for Urban Wage Earners, Clerical Workers, all items (Los Angeles - Long Beach -
Anaheim areas)," published by the United States Department of Labor, Bureau of
Labor Statistics (the "CPI") in effect on the adjustment date and the CPI in
effect on January 1, 1984. Should the Bureau of Labor Statistics discontinue the
publication of the CPI, or publish the same less frequently, or alter the same
in any manner, then the Company may adopt a substitute index or substitute
procedure which reasonably reflects and monitors consumer prices. A decline in
the CPI shall not serve as a basis for a reduction in the bi-weekly or semi-
monthly payments to be paid to or on account of the Executive.

     Section 3.4:  STOCK OPTIONS
                   -------------

               The Company shall amend all outstanding Stock Option Agreements
     with the Executive to provide, and shall provide in all future options
     under the Company Stock Option Plan or future stock option plans, that the
     Executive may accelerate the exercisability of all options to acquire
     shares covered by such Stock Option Agreements, and by future agreements
     (i) on the termination of the Executive's employment by the Company for any
     reason, or (ii) the occurrence of a "potential change in control of the
     Company."  For the purpose of this provision, a "potential change in the
     control of the Company" shall be deemed to have occurred if (i) the Company
     enters into an agreement or letter of intent the consummation of which
     would result in the occurrence of a "change in control of the Company," as
     hereinafter defined, (ii) any person (including the Company) publicly
     announces an intention to take or to consider to take actions which if
     consummated would constitute a "change in control of the Company" or (iii)
     the Board of Directors of the Company adopts a resolution to the effect
     that, for the purpose of this provision, a "potential change in

                                                                               7

     control of the Company" has occurred.  For the purposes of this provision,
     a "change in control of the Company" shall be deemed to have occurred if
     (i) any "person" (as such term is used in Sections 13(d) and 14(d) of the
     Securities Exchange Act of 1934, as amended (the "Exchange Act"), other
     than a trustee or other fiduciary holding securities under an employee
     benefit of the Company, is or becomes the "beneficial owner" (as defined in
     Rule 13d-3 under the Exchange Act), directly or indirectly, of securities
     of the Company representing 25% or more of the combined voting power of the
     Company's then outstanding securities regardless of whether or not the
     Board of Directors shall have approved such change in control, (ii) the
     shareholders of the Company approve (a) a merger of consolidation of the
     Company with any other corporation regardless of which entity is the
     surviving company, other than a merger or consolidation which would result
     in the voting securities of the Company outstanding immediately prior
     thereto continuing to represent (either by remaining outstanding or by
     being converted into voting securities of the surviving entity) at least
     80% of the combined voting power of the voting securities of the Company or
     such surviving entity outstanding immediately after such merger or
     consolidation or (b) a plan of complete liquidation of the Company or
     agreement for the sale or disposition by the Company of all or
     substantially all of the Company's assets, (iii) during any period of two
     consecutive years, individuals who at the beginning of any such period
     constitute the Directors of the Company cease for any reason to constitute
     at least a majority thereof unless the election, or the nomination for
     election by the Company stockholders, of each new Director of the Company
     was approved by a vote of at least a majority of such Directors of the
     Company then still in office who were Directors of the Company at the
     beginning of any such period, or (iv) any other event shall occur that
     would be required to be reported in response to Item 6(c) (or any successor
     provision) of Schedule 14A of Regulation 14A promulgated under the Exchange
     Act.

     Section 3.5:  POTENTIAL EXCISE TAXES
                   ----------------------

               Should any payments hereunder or contemplated hereby be subject
     to excise tax pursuant to Section 4999 of the Internal Revenue Code of
     1986, or any successor or similar provision thereto, or comparable state or
     local tax laws, the Company shall pay to the Executive such additional
     compensation as is necessary (after taking into account all Federal, state
     and local income taxes payable by the
<PAGE>
 
                                                                               8

     Executive as a result of the receipt of such compensation) to place the
     Executive in the same after-tax position he would have been in had no such
     excise tax (or any interest or penalties thereon) been paid or incurred.
     The Company shall pay additional compensation upon the earlier of (i) the
     time at which the Company withholds such excise tax from any payments to
     the Executive or (ii) 30 days after the Executive notifies the Company that
     the Executive has filed a tax return which takes the position that such
     excise tax is due and payable in reliance on a written opinion of the
     Executive's tax counsel that it is more likely than not that such payment
     with respect to any such excise tax is due and payable.  If the Executive
     makes any payment with respect to any such excise tax as a result of an
     adjustment to the Executive's tax liability by a Federal, state or local
     authority, the Company will pay such additional compensation within 30 days
     after the Executive notifies the Company of such payment.  Without limiting
     the obligation of the Company hereunder, the Executive agrees, in the event
     the Executive makes any payment pursuant to the preceding sentence, to
     negotiate with the Company in good faith with respect to procedures
     reasonably requested by the Company which would afford the Company the
     ability to contest the imposition of such excise tax; provided, however,
     that the Executive will not be required to afford the Company any right to
     contest the applicability of any such excise tax to the extent that the
     Executive reasonably determines that such contest is inconsistent with the
     overall tax interests of the Executive.  The Company agrees to hold in
     confidence and not to disclose, without the Executive's prior written
     consent, any information with regard to the Executive's tax position which
     the Company obtains pursuant to this Section 3.5.

     Section 3.2:  Participation in Other Benefits, shall be amended to

     in scope and amount as those received by any other employee of the Company

     Executive's employment is terminated pursuant to Section 1.2(b), Section

     the preceding two years and that he would be entitled to receive a pro rata
     portion of such amount for any period shorter than a full calendar year;
     (ii) the amount of the profit sharing plan contributions otherwise made on
     behalf of the Executive shall be determined assuming that the level of
     Company contributions to the plan would equal the average of such levels
     for the preceding two years; and (iii) the payment for the value of welfare
     benefits shall be based on the current cost of such coverage to the Company
     and shall take into account the Executive's benefit plans for retirees (if
     he would have qualified for such participation assuming he had an
     additional three years of service)."

XI.    At-Will Employment and Severance Arrangements
       ---------------------------------------------

          By accepting employment on the terms set forth in this offer letter,
you agree that your employment and compensation are at-will and therefore can be
terminated, with or without cause, at any time, and without prior notice, at
your option or the Company's option.  This at-will employment relationship will
remain in effect throughout your employment with the Company, unless it is
specifically modified by an express written employment agreement, authorized by
the Company's Board of Directors.

          No CalMat employment policy, nor any written or oral statement or
promise, nor any course of conduct, practice, award, promotion, transfer, or
length of service creates an express or implied contract modifying this at-will
relationship.  Your acceptance of at-will employment with CalMat is a material
part of this offer of employment and is an express condition of your employment.

          In the event that CalMat at any time chooses to exercise its right to
terminate you without cause, you will be paid one year's base salary, less
legally required deductions and withholdings, as severance pay.  In addition,
CalMat will waive payment of costs of continued health coverage under COBRA for
one year.  These will be the only payments to which you will be entitled in the
event of termination without cause.

          Enclosed for your information and consideration are materials
describing CalMat's benefit programs and personnel policies, and copies of the
Company's latest Annual Report and related documents, as listed on the
attachment to this letter (sent under separate cover).

          Bruce, we are very excited about your joining CalMat, and we look
forward to having you on board.

                                         Very truly yours,

                                         /s/ A. Frederick Gerstell
