Gentlemen: -
In accordance with your request, conformance testing has been performed on the Class C3 asphaltic
concrete materials sampled from the referenced project site on August 26, 1991. The paving contractor
was A.B.C. Construction and the asphalt concrete was supplied by Southcoast Materials. Laboratory and
field test results are submitted on Tables .A and B.
It should be noted that in-place density tests 4, 43, 45, 47, 48, 49, 52, 56, 58, 69, 71, 73, 77, and 78
do not meet a relative compaction requirement of 95 to 100 percent, however, the average in-place
relative compaction is acceptable. .
We appreciate the opportunity to provide our Materials Testing services.

GENTLEMEN:-
In accordance with the request of Mr. Jay Hall, we have
performed a sieve analysis (ASTM D 422) , sand equivalence
(CALTEST 217Y, Resistance Value (CALTEST 301) , and Durability
Index test on the sample of Class II aggregate base material
which was supplied toour, firm by South Coast Materials
Company, Inc. on April 2, 1991. 'The results obtained,
presented on the attached Plate No. 1, indicate 'that the soil
sample submitted was in compliance with section 26-1 of the
State of California Department of Transportation Standard
Specifications.
If you should have any questionsafter reviewing this report,
please do not hesitate to contact this office. This
opportunity to be of professional service is sincerely
