Effect of Gypsum and Polyester Fibers on Compaction and CBR Value of Fine Grained Soil

In this paper we center around the improvement of designing properties of soil by utilizing polyester fiber and gypsum treating with the fine-grained soil. In this polyester fiber and gypsum mixing with the fine-grained soil to upgrade the designing properties. The point of the present examination is to decide the polyester fiber geo material as soil stabilizer. This investigation talks about the capability of fine-grained soil adjustment with polyester fiber and gypsum as admixture. The shifting rate 0.5%, 1%, 1.5% of polyester fiber and 2% ,4%,6% of gypsum was blended with fine grained soil. All the California bearing ratio Tests were directed at various blend creations of polyester fiber and gypsum with fine grained soil. The value of CBR increases with the increasing proportion of polyester fiber and gypsum, in this mixing the value increases up to 1% of polyester fiber after that the value start decreasing. The pavement is designed with the help of IRC 37:2012 which shows reduction in the thickness of pavement leads to cost effective approach.
