Abstract

Nonreproducible relative density test results for an hydraulic fill of clean river sands, suggested errors either in assumed control densities or methods or techniques of field testing. Control densities had been assumed to vary only slightly because sample gradations and sizes appeared quite similar. To verify this assumption, separate maximum and minimum density (ASTM Test for Relative Density of Cohesionless Soils, D 2049-69) and gradational parameters were determined for each field density test. No dependable correlation of maximum or minimum densities or range between them with gradational characteristics was apparent for results reported.
