Soil improvement is one of the methods of soil reinforcement. One method of soil improvement is the addition of soil with lime (CaO). The swelling soil (expanding when wet conditions, and shrinking when dry conditions) is identified from the value of soil activity. The behavior of soil activity decreases with increasing CaO, but for soils in weathered volcanic areas (volcanic breccia and lava) as in Jatinangor, with the value of high soil activity, the optimum addition of CaO to the soil is 15%
