FIELD REPORT
3.00
The undersigned arrived on site, as requested, to re-observe the compaction of soils for Lot 2R
Pavement Subgrade. Please see the attached sketch.
Utilizing the nuclear test method to check the compaction of soils; test results indicated that the
compacted material, at the areas and elevations tested, met or exceeded the project
requirements of 95% of the maximum dry density with a moisture content above optimum, as
obtained in our laboratory using the Standard Proctor Method (ASTM D-698).
Locations and elevations of all tests are based on stakeout provided by others. We cannot be
responsible for structures located off of the observed engineered pad, misaligned utilities or
stakeout errors causing uncontrolled fill to be placed in structural areas.
The failed density tests from Report 41 (09-3-19) were re-tested and passed on this date.
