In accordance with your request, our firm has obtained field
density tests in the compacted base materials of Elm Avenue,
Carlsbad Tract No. 74-14 (A), Carlsbad, California.
Our field soil' technician obtained field density tests in the
compacted base materials requested by the Construction Inspector
with the City of Carlsbad. The field density tests were obtained
in accordance with A.S.T.M. Test Hethod D 1556. Moisture
determinations were made from each in-place field density test.
The density tests shown in this report are a complete summary of
tests obtained on Augu~t 7, 1980.
A laboratory compaction test was performed on the typical base
materials. The compaction test was performed in accordance with
lLS.T.M. Test Method D 1557 (four inch diameter mold, five layers,
25 blows each layer, 10 pound hammer, 18 inch drop, using all
material passing a No. 4 sieve). The laboratory compaction test
represents the theoretical value to which it is possible to compact
the soil in the field with the proper compactive effort.
The relative compaction as summarized on Figure No. I is the ratio
of the field density to the maximum laboratory density expressed
as a percentage for the comparable material.
Our test results indicate that the base materials were properly
placed and compacted to at least 95 percent of maximum dry density.
This opportunity to be of service is sincerely appreciated.
Respectfully submitted,
