FINAL REPORT OF TESTING AND OBSERVATION SERVICES
PERFORMED DURING SITE IMPROVEMENTS
Gentlemen:
In accordance with your request and our Proposal No. LG-06175 dated April 27, 2006 we have
provided compaction testing and observation services during the construction of site improvements at
the subject project. Our services were performed during the period of May 8, 2006 through
August 16, 2006. The scope of our services included the following:
Performing in-place density tests on a "call out" basis during utility trench backfill operations
including storm drain, water, and joint trench backfill. Additionally, in-place density tests
were performed during the preparation of sidewalk, curb and gutter and roadway subgrade
and the placement of aggregate base and asphalt concrete pavement.
Providing geotechnical consultation during improvement operations.
Performing laboratory tests to aid in evaluating the compaction characteristics of various soil
conditions encountered, including asphalt concrete and base materials.
Preparing this final report of improvements.
To aid in preparing this report, we have reviewed the following report and plans associated with the
project improvements:
1. Final Report of Testing and Observation Services Performed During Site Grading, Villages
of La Costa, Neighborhoods 1.02 & 1.03, Carlsbad, California, performed by Geocon
Incorporated, dated April 3, 2006 (Project No. 06403-52-22).

Final Report of Testing and Observation Services Performed During Site Grading, Villages
of La Costa, Neighborhood 1.01, Carlsbad, California, performed by Geocon Incorporated,
dated March 13, 2006 (Project No. 06403-52-22)
Public Street & Utility Plans for La Costa Greens, El Camino Real Widening, Drawing
No. 397-2R, prepared by Hunsaker and Associates, City of Carlsbad approval dated April 10,
2006.
In-place density tests were performed using a nuclear density gauge in accordance with ASTM Test
Procedures D 2922-01 and D 2950-91 for soil and asphalt concrete, respectively. The results of the
in-place density tests are summarized in Table I. In general, the results of the in-place density tests
indicate that the utility trench backfill and sidewalk subgrade materials possess a dry density of at
least 90 percent of the laboratory maximum dry density at the locations tested. In-place density test
results indicate that the curb/gutter and roadway subgrade, as well as aggregate base materials
possess a dry density of at least 95 percent of the laboratory maximum dry density at the locations
tested. In-place density test results indicate that the asphalt concrete is compacted to at least 95
percent of the Hveem density at the locations tested.
Laboratory compaction tests on representative soil samples were performed in accordance with
ASTM Test Procedures D 1557-02 (maximum dry density and optimum moisture content), D 422-63
(particle size/sieve), D 2419-02 (sand equivalent value). Laboratory tests on asphalt concrete samples
were performed in accordance with ASTM Test Procedures D 2726-04 (Hveem density), D 2041-03a
(theoretical maximum density), D 1560-92 (asphalt concrete stability), D 6307-04 (asphalt content),
and C 136-05 (sieve analysis for asphalt). The results of laboratory tests are summarized in Tables II
through VI.
Laboratory tests on base materials and asphalt concrete were performed to check conformance with
Standard Specifications for Public Works Construction (Greenbook) and Standard Specifications,
Caltrans. The results of the laboratory tests indicate the samples are in general conformance with the
exception of those in bold type. These results have been reported to the Morrow Development on-site
superintendent and to the City of Carlsbad representative. It should be noted that Section 203-6.3.3 of
the City of Carlsbad Asphalt Concrete Special Provisions states, Deviations in gradation may be
considered in conformance with the mix design provided the stability of the completed mix complies
with the requirements for Stabilometer Value per Table 203-6.3.2 (A) Marshal Stability using Asphalt
Institute MS-2. The results of our laboratory asphalt tests are summarized in Table III and indicate
that the asphalt concrete samples met or exceeded the required stability values of 33 and 35 for 'i"2-
and 3%-inch asphalt, respectively.
Adequate drainage provisions are imperative. Under no circumstances should water be allowed to
pond adjacent to improvements. Finish grades should be established so that drainage water is directed
away from pavements, curb and gutters, and sidewalks to controlled drainage devices. Irrigation of
Project No. 06403-52-28 - 2 - October 13, 2006
landscape areas adjacent to pavements should be monitored to provide just enough water to support
plant life.
Should you have any questions regarding this report, or if we may be of further service, please
contact the undersigned at your convenience.
Very truly yours,

EXPLANATION OF CODED TERMS
- TEST SUFFIX
A, B, C,... : Retest of previous density test failure, following moisture conditioning and/or recompaction.
Fill in area of density test failure was removed and replaced with properly compacted fill soil.
- PREFIX CODE DESIGNATION FOR TEST NUMBERS
AC - ASPHALT CONCRETE B - BASE
CG -CURB AND GUTTER RW - RECLAIMED WATER
SD - STORM DRAIN SO - SUB GRADE
SW - SIDEWALK WL - WATER LATERAL
CURVE NO.
Corresponds to curve numbers listed in the summary of laboratory maximum dry density and optimum
moisture content test results table for selected fill soil samples encountered during testing and observation.
- ROCK CORRECTION
For density tests with rock percentage greater than zero, laboratory maximum dry density and optimum
moisture content were adjusted for rock content. For tests with rock content equal to zero, laboratory
maximum dry density and optimum moisture content values are unadjusted.
SC: Sand Cone Test (ASTM D1556)
NU: Nuclear Density Test (ASTM D2922)
OT: Other
- ELEVATION/DEPTH
Test elevations/depths have been rounded to the nearest whole foot.
