Experimental Study of the Effect of a Compacted Lime-Treated Loess on Its Hydraulic Conductivity

Abstract

In this paper, the influence of the lime content on the compaction characteristics and saturated hydraulic conductivity of lime-treated loess is studied experimentally. The test results reveal that as the maximum dry density d r max $$ \\left({d}_{r_{\\mathrm{max}}}\\right) $$ decreases, the corresponding value of optimum moisture increases with increasing lime content, and the relationship between lime content and d r max $$ \\left({d}_{r_{\\mathrm{max}}}\\right) $$ is nonlinear. On a semi-logarithmic scale, the relationship between the void ratio and the saturated hydraulic conductivity of the lime-treated soils is a cluster of parallel lines with intercepts that are related to the lime content.
