DP/MP: Density Pass / Moisture Pass
Tests are "Direct Transmission" (Method A) unless probe depth is noted as
"Backscatter". Gauge calibration data on file with the testing agency.
This report presents opinions formed as a result of our observations of soil compaction. We have relied on the contractor to continue applying the recommended
compactive effort and moisture to the fill during times when our observer is not observing operations. Tests are made of the soils only as believed necessary to
calibrate our observer's judgement. Test data are not sole basis for opinions on whether the soils meets specifications. These test results only apply to the
samples which were tested. The testing report shall not only be reproduced, except in full, without the written approval of Kumar and Associates, Inc. Nuclear
gauge density testing performed in accordance with ASTM D6938.
