Depok residual soil has generally been used as sub grade layer for road pavement. By applying lime stabilization, the California Bearing Ratio (CBR) of sub grade Depok residual soil is expected to improve. In the present work, the lime stabilization was applied by adding 10 percent of dry weight of soil and furthermore the soil lime samples were compacted by Modified Standard Proctor around the optimum water content of 31.10 %. The soil lime samples were prepared in two conditions. The first condition, the soil lime samples were cured for 0, 6, 24, 72 and 168 hours and then compacted, while in the second condition, the soil lime sample were compacted first and then cured for similar time. After this stage, the laboratory testing such as CBR and Unconfined Compression Test (UCT) were conducted on the samples. The result from this test indicated that the soil samples that were compacted first and then cured are better than the soil lime samples were cured first and then compacted. Using lime stabilization, the unsoaked CBR values increase from 50.72 % to 54.55 % and the soaked CBR values relatively did not change but decreased from 11.35 % to 10.57 %. Based on the results of laboratory tests carried out in this study, it was found that soil lime stabilization on Depok residual soil did not significantly alter both the soaked and unsoaked CBR values of the soil in the long term. However, it increases the strength of the soil provided it is not soaked.
