Compaction Behaviour of Akure Sandy Clay Loamy Soils

Abstract

Laboratory investigations were conducted to study the behaviors of sandy clay loam soil under uni-axial compression loading. The effects of applied pressure and moisture content on bulk density of soils were observed and subjected to regression analysis. The effect of applied pressure on bulk density could be described by a number of compaction behaviour equations. The equations were those of power, logarithmic, exponential and linear function with very high values of R2, while the power function seemed to be the best model to describe the behaviour. The soils were very sensitive to water content during the time of compaction. The percentage increase in soil compaction related more to changes in water content than to applied pressure.
