Stabilization of Soil by Using Polypropylene Fibers

Abstract

Abstract: This types of soil need to be stabilized in order to increase the shear strength of the soil, durability of the soil as well to prevent from the erosion. Various case studies have been carried out for these types of soil to increase the soil properties. In this case study raw fibre known as polypropylene fibre have been used to increase the soil properties and interlocking of the soil and has become the one of the major practices used in construction work. This paper purposes to conduct the case study to check the improvements in properties of sandy soil by adding raw material polypropylene fibre. Several lab tests have been carried out using varying percentage of reinforcement (0.05%,0.10%,0.15%,0.20% and 0.25%). The soil parameters like specific gravity, plastic limit, liquid limit, compaction test and direct shear test are studied. The results obtained, will strained towards the usability and effectiveness of the fibre reinforcement in the replacement of the deep foundation.
