Scope
This report presents the results of our "R" Value Determination
and Paving Recommendations for the construction of new street
Andrea Circle and the expansion of Walcott Lane in the City of
Temecula, California.
Investigation was authorized to determine the existing soil and
to provide data and specific recommendations relative to the
proposed parking and driveways as requested by the contractors,
and the construction of the new streets for the development.

Walcott Circle, respectfully, following are the recommendations.
The T.I. to be chosen by the city engineer, Mr, Ali Murktabar on
7-13-99. This report is subject to review by the governing
agencies.
Testinq
Representative samples of subbase soil were obtained from the
proposed areas to be paved. The samples were tested in accor-
dance with the State of California Test Method 301D, latest revi-
sion. The "R" Values test data are detailed on Plates "A" and
"BIt.

The subbase soil shall be compacted to a minimum of 90%. The
depth of scarification and processing shall be 12 inches minimum.
The baserock compacted to 95% of its maximum density.
The asphalt shall be either AR 4000 or AR 8000 or equivalent.
The asphalt shall be placed and compacted to at least 96% of its
maximum density. The thickness noted above must be attained.
Verification of the thickness may be required by coring the as-
phalt paving. The asphalt lay down should be observed by this
office if required by the City Temecula, California.
The compaction standard is A.S.T.M. D-1557
The life of the asphalt is directly proportional to its upkeep
and maintenance. Over-stressed pavements results in shorter
life.

Recommendations (cont'd)
Alligator or fissure cracks, if they appear, must be repaired im-
mediately. Admittance of moisture rapidly decreases the strength
required to perform well under variable climatic conditions.

fice.
