Abstract :
In general, clay soils have high plasticity and swellability relatively high loss. If a civil engineering structure is built on clay then problems will arise on the land itself, namely the occurrence of settlement and slides. It is very important to know the land problem, and make efforts to improve it. To overcome the poor clay soil, it is necessary to soil improvement. Soil improvement can be done in two ways, namely: mechanical method and chemical method. The method of improving clay soil with The chemical method used is using lime and wood sawdust, Stabilization with lime can increase the value of soil plasticity and increase quite real. The use of wood sawdust was chosen as a stabilizing material because contains fiber, and can fill the pores of clay and improve the density of the clay. The test aims to knowing the stability of the soil, and knowing the effect of adding sawdust on the physical properties of the soil. To find out the plasticity of the soil, it is necessary to do by using the composition of clay and lime and powder materials wood saw with mixed composition, 7% (3%sgk+4%lime), 14% (6% sgk + 8% lime), 21% (9% sgk + 12% lime), 28% (12% sgk + 16% lime) and fermented for: 7, 14, 21, and 28 days. In this study, the results of soil changes for the better at a mixture of clay with lime and wood sawdust with mix 28% 21 days
