Abstract

Expansive soil is soil containing very high mineral montmorillonite which is sensitive to water, high shrinkage, and low bearing capacity. Therefore, an effort is needed to solve this problem by performing soil stabilization to increase the soil in terms of bearing capacity, increased stability, and reduced settlement so that it can be used as subgrade in a construction. Soil from Gedebage, a region in Bandung, became the test subject in this research. From the results of physical testing, the soil from Gedebage is an expansive soil with a plasticity index value of approximately 48%. The stabilization method was carried out in this research by mixing additives in the form of bledug kuwu mud and vermiculite to investigate their effects on strength and swelling. In this research, a preliminary test was carried out by mixing the content of bledug kuwu of 5%, 10%, 15%%, and the vermiculite content of 4% was used for all tests. Furthermore, the treatment was conducted by curing the samples that had been made for 0 days, 3 days, and 7 days. The results showed that the addition of mixed materials consisting of bledug kuwu mud and vermiculite contents of 15% bledug kuwu mud, and 4% vermiculite, respectively can increase the bearing capacity of expansive soil and reduce its swelling.
