The objective of the study was to investigate the relationship between the dilatometer modulus (ED) and the constrained modulus (M) for compacted soils. An experimental program was designed using three natural soils encountered in North Carolina compacted at optimum moisture content. For the compacted soils studied, it was found that current methods for interpreting dilatometer data to predict compressibility, as determined from one-dimensional compression tests, significantly overestimated the values that were measured. On the basis of the combination of laboratory and field tests conducted, it would appear reasonable to accept the dilatometer modulus as an upper bound to the anticipated in situ constrained modulus, with she realization that values may actually be in the range of 50 to 80 percent of that value, depending on soil type.
