Soil Moisture Conditions and their Effects on the Engineering Properties of Compacted Soils

Abstract

As the properties of compacted soil conditioned for a construction work may change after the construction is completed, it is essential for a reliable design for the construction to investigate not only the strength of the compacted soil directly after compaction but also the future strength of it. In either case the strength of the soil is affected mainly by the moisture content and the dry density. For this purpose the authors studied in this paper several subjects concerning (a) qualitative moisture scales to estimate future moisture condition, (b) the effect of moisture content and dry density on the strength of compacted soil, and (c) future moisture content and future dry density of compacted soil.
