Abstract

This study investigated the impact of compactive efforts on A-7-5 lateritic soil stabilized with Bamboo Leaf Ash (BLA) mixed with lime.  Preliminary tests were conducted on the soil sample for identification and classification. Compaction tests (using British Standard Light  (BSL), British Standard Heavy (BSH) and West Africa Standard (WAS) compactive efforts) were performed on the sample in both natural  and stabilized states by incorporating 2, 4, 6 and 8% Bamboo Leaf Ash mixed together with 1, 2, and 3% lime by weight of soil sample.  Maximum dry density (MDD) increased to 1766 kg/mat 3% lime and 6% BLA, 1818 kg/m3 at 3% lime and 8% BLA and 1866 kg/m3 at 3%  lime and 2% BLA while the optimum moisture content decreased to 12.70% at 3% and lime 8% BLA, 11.40% at 2% lime 6% BLA and 11.12%  at 3% lime and 2% BLA for BSL, WAS and BSH, respectively. Based on these findings, the addition of lime-BLA enhanced the soil and has a   promising prospect for stabilization of lateritic soil.
