● The geotechnical
engineer was on site to perform compaction testing of areas being backfilled.
Most areas tested passed compaction at or above the 90% density
specified. Two areas tested failed compaction at 86% density and 7%
moisture, so the areas around and surrounding those tests were re-rolled and
tested again. All remaining locations passed at 90% to 95% compaction and
6-9% moisture. Moisture content was above ideal content of 5 to 7%, but
some of the borrow source material was more sandy than what was tested to
determine moisture content. According to the geotechnical engineer, the
sandier material requires more moisture to achieve specified density.
