Abstract

The results reported in this study indicate that careful control of the applied torque settings and instrumental modification can play an important part in the determination of particle size distributions of soils using the dry sieving technique. Determinations were highly repeatable and increased the sensitivity of the method for comparative soil analyses used to test for similarity. Experimental results also suggested that equal weights of soils should be compared in the determinations of both control and questioned samples.
