Abstract - Differential settlements, inadequate strength, and high compressibility are challenges when building on weak or soft soils. Because they are weak, clayey soils will not adequately sustain a pavement, which will ultimately affect how well it performs and how long it lasts. To increase the load bearing capacity of soil, a number of strategies are available, including soil stabilization and supplying reinforcement. The successful use of industrial wastes as a stabilizer is made possible by soil stabilization, one of the modification techniques used to enhance the geotechnical properties of soil, which has grown to be a key practice in construction engineering. Because it is accessible and adaptable, this method is growing in popularity. The process of stabilizing waste materials allows for the creation of low-cost road building. The current article details a study that was conducted to see if adding Terrasil and Coir Fiber improved the qualities of clayey soil. To get the ideal admixture % needed for soil stabilization, unmodified soil is mixed with Terrasil and Coir Fiber in a range of percentages. For both modified and unmodified clayey soil, laboratory experiments such Atterberg's limit, Compaction test, CBR test, and UCS test were conducted as part of this comparative study. In this study Terrasil and Coir Fiber were used to stabilize Expansive soil. Using index properties tests Coir Fiber was fixed at 1.5% respectively. Terrsail was then varied (i.e. 0.3%, 06% and 0.9%).
