RAPID METHOD OF SUBGRADE COMPACTION AND PERFORMANCE EVALUATION

The dynamic modulus and its variations with time are predicted from dynamic deflections by using elastic layers theory. Field moisture and density variations are measured by using deep probe nuclear equipment. Undisturbed field samples were obtained just after construction and a year or two later. Laboratory testing showed agreement with field measurements, and it is concluded that the subgrade gains moisture after construction and suffers loss of density and modulus. Simulation of seasonal variations (saturation and freeze-thaw in an open system) was conducted in the laboratory, and the trends agreed closely with those obtained from the field.
