SUMMARY The packing of sands was studied over a range of moisture contents using both static loads and impacts from a Bruce compactor. Particle shape and particle size distribution were found to determine the maximum and minimum void ratio to which a sand would pack. For narrowly graded sands, air‐dry and nearly saturated sands were always found to pack more closely under a given load than the same sand at any other moisture content. There was practically no variation of packing with moisture content over a wide range of intermediate moisture contents. The bulk density attained after impact loading depended on the bulk density prior to impact and increased with the logarithm of the number of impacts. An attempt is made to give a physical explanation for these results and to relate results obtained by static loading and Bruce compaction.
