Abstract

In practice, it is quite common for soils to be mixed and compacted at moisture contents lower than the optimum moisture content (OMC) or lime content less than the optimum lime content (OLC). This study investigates the effect of not achieving the target of OMC or OLC on the volumetric behavior (swelling and shrinkage) and swelling pressure under swell–shrink cycles. The selected expansive clay was a residual soil derived from weathered Quaternary age basaltic rocks in Western Victoria, Australia. A series of cycles of swell–shrink tests were conducted at different initial lime contents, moisture contents, and stress levels. Vertical deformation and swell–shrink cycles' relationship were ob..
