Subject: Report of In-Place Density Test Results
Subgrade and Aggregate Base
Project: El Camino Real Sidewalk.
Carlsbad, California
Dear Mr. Cook:
In accordance with your authorization,w e-hdVe performed in-place density testing services
associated with the subgrade compaction and aggregate base placement for the El Camino Real
Sidewalk in Carlsbad, California The scope of our services consisted of in-place density testing
of subgrade and aggregate base, laboratory tests for moisture-density curves of the subgrade and
aggregate base material, and preparation of this summary of compaction test results.
-.
In-place density testing was performed on a part-time, "as-called" basis at the direction of the
City's resident project inspector. Our services were performed from October 13, 1994 through
October 24, 1994., T.D. Hays was the: .contractor, for the project. ............
The maximum dry density and optimum moisture content of subgrade soils and a representative
sample of aggregate base was evaluated in our laboratory in general accordance with ASTM test
procedure D-1557. The results of the tests are presented in Table 1 entitled "Maximum Density
Test Results."
In-place density tests of subgrade and aggregate base were performed-in general accordance with
ASTM test procedures D-2922 and D-3017 (nuclear method of determination of density and
moisture, respectively). The results of the tests at the specified locations tested are 'presented in
Table 2 entitled "Compaction Test Summary."

Testing was performed at the direction of the project inspector, and results of the in-place density
tests were reported to the project inspector either in the field at the time of testing or shortly
thereafter once the maximum density test was complete. Since our services were provided. on'. a
part-time, "as-called" basis, we did not observe placement of aggregate base and paving
operations on a near-continuous basis. Therefore, we cannot comment that all subgrade and
aggregate base have been placed and compacted in accordance with the project specifications.
Our tests have been performed in accordance with the generally accepted pavement testing
practices in the Carlsbad area at this time. No warranty, express or implied, is made.
We appreciate the opportunity to be of service. If you have any questions or need additional
information, please contact the undersigned.
Sincerely, •. S
