Abstract - Building on weak or soft soils presents issues such as differential settlements, insufficient strength, and significant compressibility. Clayey soils are weak, and as a result, a pavement will not be able to withstand it for long enough to work as intended. There are several methods available to boost the soil's ability to support more weight, such as providing reinforcement and stabilizing the soil. One way to improve the geotechnical qualities of soil is soil stabilization, which has become an important practice in construction engineering and allows for the successful use of industrial wastes as a stabilizer. This method's appeal is increasing due to its adaptability and accessibility. The stabilization of waste materials makes it possible to construct roads at a reasonable cost. The investigation that was done to determine whether adding wood ash and calcium chloride enhanced the properties of clayey soil is described in the current article. Unmodified soil is combined in a variety of percentages with wood ash and calcium chloride to produce the optimal admixture% required for soil stabilization. Laboratory tests such as Atterberg's limit, Compaction test, CBR test, and UCS test were performed for both modified and unmodified clayey soil as part of this comparative study. In this study Wood Ash and Calcium Chloride were used to stabilize Expansive soil. Using index properties tests Wood Ash was fixed at 12% respectively. Calcium Chloride was then varied (i.e. 02%, 04%, 06% and 08%).
