RECENT INVESTIGATIONS INTO THE DRY COMPACTION OF SAND

The advantages of economy in the use of water in arid areas is self evident. This paper discusses the possibility of "dry" compaction of sand. This idea stems from the fact that some naturally occurring sands, though by no means all, achieve a level of dry density when compacted dry which is equal to or higher than that produced at "optimum" moisture content by the same compactive effort. Laboratory test data on sand samples from a desert road project are presented and discussed and related published work by other authors is briefly reviewed. It is noted that there does not appear to be any simple, positive means of identifying sands suitable for dry compaction other than by laboratory compaction tests or field compaction trials. The influence of soluble salts and plastic fines is considered: the resulting aggregation of particles appears to be an important factor. The influence of dissolved salts on the surface tension of the porewater may also play a part. Other possible factors were considered but no positive trend is as yet apparent. It is concluded that full scale trials, backed by further systematic laboratory studies, are the next essential steps before any large scale application of dry compaction can proceed with confidence. /TRRL/
