On march 26, in 2004, some areas of mount Bawakaraeng landslide, carrying an expected avalance of material about 230 million cubic meters of sediment in the upstream, due to the effect on the future ruins of multi-purpose reservoir located Bili-Bili +30km downstream from caldera. There are around 75 million cubic meters of fine sediment that had accumulated in the bottom of reservoirs and nearly reaches the intake. Therefore, the effort is needed in order to maintain the stability of sediment dredging reservoir function. The purpose of this study is examine the behavior of sediment dredging Bili-bili dam with cement stabilization for rigid pavement and give solutions to optimize the bili-bili dam function in a way to dredge the sediments around the intake dam, but the impact on the accumulation of material (material dumping) and damage the environment. While the other parties would need the land for road construction is increasing, but the soil is limited and expensive. By looking at the problem, this study tries to make an assessment of sediment dredging to be used as a soil base (subgrade). The improvement of the sediment was conducted with a number of tests such as physical tests, chemical, and minerals to determine the characteristics of actual dredging sediment continued with stabilization of the soil sample, namely mixing with cement binder percentage and curing time, and then conducted laboratory tests to look at mechanical index. Results of laboratory tests were then conducted the test model with rigid pavement loading, to find a large decline in sediment material from the subgrade, cement stabilization of loading, the result of the analysis in the form of graphs the relationship between the moduls of subgrade reaction (k) with some of the CBR as a model validation data.
