Abstract :
Expansive clay is soil that has the potential to expand and shrink when it reacts with water. Expansive soil is soil or rock whose clay content has the potential for shrinkage due to changes in water content. Soil stabilization is done by mixing or adding other materials. The additional material used is obtained from industrial waste, namely Bottom Ash and Waste Dry Dust Collector. This research was conducted with several samples and test objects that aim to compare the results obtained so that it becomes an innovation. The test object used in this research is expansive soil mixed with Bottom Ash and Waste Dry Dust Collector (WDDC) with a mixed variation of 0% and 2.5% for each test GS, Atterberg Limit, compaction, CBR (soaked and unsoaked). , Swelling and UCS. The results of the analysis found that the best CBR value was found in the soil variant mixed with 2.5% BA and 2.5% WDDC with an increase in CBR value of 196,91% from the original soil CBR. Soil with 2.5% WDDC succeeded in reducing the swelling value by 16% from the original soil swelling value. The value of the free compressive strength (qu) experienced the largest increase, namely 62% from (qu) the original soil at 2.5% BA and 2.5% WDDC variants.
