Abstract
The minimum and maximum void ratios, corresponding to states of dense and loose random packing, are the most meaningful measures of packing behaviour. Size distribution, sphericity, roundness and surface roughness of sand particles, all affect the packing and compressibility of sands. Size affects packing, only when particles are less than 50 μm. Maximum and minimum void ratios decrease with increasing roundness and sphericity. For narrowly graded sands, compaction is almost independent of moisture content except near air-dryness and near saturation, where it is greater. The influence of both sand-particle size distribution and particle characteristics on compaction and plow-pan formation in sandy soils is discussed.
