Abstract

Basically, clay soils have high plasticity properties, relatively high shrinkage swelling power, and low bearing capacity or soil strength. If a civil engineering structure is built on clay soil, there will be problems with the soil itself, namely settlement and sliding. To overcome the bad clay soil, it is necessary to improve the soil. Soil improvement can be done in two ways, namely: mechanical method and chemical method. The method of improving clay soil by chemical means is using lime and bagasse ash. Stabilization with lime can increase the UCS value of the soil and the increase is quite significant. The use of bagasse ash was chosen as a stabilizing agent because it has loose properties so that it can be a filler and reduce the cohesion of the clay. Testing on the swelling potential value and soil bearing capacity (UCS Test) It was carried out by mixing clay and lime and bagasse ash with mixed variations, 0%, 8% (4%aat + 4% lime), 16% (8% aat + 8% lime), 24 (12% aat + 12% lime) and ripened for: 7, 14, 21, and 28 days. In the swelling test, the optimum value for a mixture of 24% curing 28 days was IP = 9.8%, including the category of low swelling. While the results of the UCS test got the optimum value in a mixture of 24% curing 28 days of qu = 1.240 kg/cm² including stiff clay/stiff. From this research, it can be concluded that the greater the percentage of lime and bagasse ash mixture that is added, the harder the soil becomes.
