PRECISION OF THE RELATIVE COMPACTION TEST USING MUCLEAR GAGES

Precision statements for the relative compaction test under varying conditions are given. The precision of the in situ density determination is based on application of Test Method No. Calif. 231-F utilizing nuclear gages and a sampling technique called the area concept. Maximum wet density precision is based on ASTM-D1557-70. A model for nuclear gage repeatability is established and the adequacy of current calibration procedures is evaluated. The precision of ASTM-D1557-70 using California operators is reported. A number of pertinent variance components are isolated with respect to the overall relative compaction variance. Also, the variation of density determinations within a relatively uniform area is given for treated and untreated soils. Precision statements for a number of California concrete and aggregate test methods are also summarized.
