Abstract

In recent decades, the accumulation of discarded tires has resulted in environmental issues all around the world. Using recycled tire material to enhance the characteristics of problematic soils is the piratical solution to this problem. This article reports an experimental investigation of the effect rubber granulated on .expansive soil sample from shahat city was mixed with different percentages (0%, 2%, 4%.6%,8%,10%, and 15%)by weight of granulated rubber. The compaction and unconfined compressive strength tests are carried out on natural samples and samples added with (2%,4%,6%,8%,10%and 15% rubber granulated. according to the results of the test, the maximum dry density decreased when increasing the rubber content and increasing the optimum water content until reachto8%. The maximum unconfined compressive strength through 3 days at approximately 2%. The Granulated Rubber and soil mixture played a role in postponing the crack development.
