| Summary: | Scrap tires are undesired urban waste and the volume is increasing every year. Tires have characteristics that make them not easy to dispose, and potentially combustible. Utilizing waste materials as an alternative to using virgin construction materials, made from nonrenewable resources, in civil engineering applications is currently one of the most important environmental issues. The unique properties of tire chips such as strength, high frictional resistance and flexibility can be exploited in a beneficial manner in geotechnical applications. In this research, tire chip mixed randomly with various percentages by weight up to 30% of sand and two different sizes of tire chip. Laboratory California Bearing Ratio (CBR) and other laboratory model tests are conducted to investigate the benefits of using tire chips as lightweight inclusion to improve the bearing capacity and control settlement of strip footing on sandy soil. The results indicate that the addition of tire chip increase the CBR strength of the sand significantly, it’s about 29% for size (5-9) mm and 19.5% for size (10-20) mm at the tire chip percentage of 20%, improved the bearing capacity and modifies the load -settlement behavior of the footing Sice the used of tire chips reduced settlement about 22%.
