USE OF NUCLEAR SOIL MOISTURE AND DENSITY EQUIPMENT FOR DETERMINATION OF VOLUME CHANGE FROM CUT TO FILL

An investigation to estimate the volume change that could be expected in removing soil materials from cut areas and compacting them in fill was undertaken with the aid of nuclear soil moisture and density equipment. The procedure for boring holes for the casings was described. The first readings with the nuclear probes were taken at the 1-ft level because operation of this equipment is restricted to a minimum depth of 1-ft. In order to measure the moisture content and density of the top foot of soil it was necessary to use the surface nuclear soil and density probes. Since it was not possible to determine in advance of construction the exact average density of the soils that would be obtained in the field it was recommended that 95% of modified Proctor maximum density figure be used pursuant to field density measurements during construction. At the time of this report final results as to average compaction obtained and amount of volume change were not available. It had been estimated that a substantial saving was realized by altering the grades based on the computed volume change figure rather than using the original grades which were based on the premise of a 10% shrinkage.
