Strength and Swelling Behavior of Black Cotton Soil Stabilized with Waste Rubber Tyre

Objectives: To determine the strength and swelling behavior of black cotton soil (expansive soil) using a shredded rubber tyre as an additive. Methods: Series unconfined compressive California Bearing Ratio (CBR) tests were carried out on mixed with 0%, 5%, 10%, 15% tyres, results compared untreated samples. The study also investigated influence characteristics by performing pressure test. Findings: From experimental results, it is inferred that optimum addition 10% can effectively improve soil. stabilized increased 32 % 49.3% respectively to An illustration presented shows effect CBR in terms reduction 18% pavement thickness. This may reduce total cost project. present potential Black found be decreased 33.33% for Novelty: use expansive its value, leading Hence, lead further Also, disposal problem waste tyres resolved up certain extent.
