Improvement of geotechnical properties of soil has become a common practice in construction engineering as it ultimately leads to a sufficiently strong and durable foundation which is the most important part of any construction work and this process is termed as soil stabilization This project aims at investigating the use of polypropylene fiber as a soil stabilizer and to evaluate the effect of it on different properties of soil such as Liquid Limit, Plastic Limit, Plasticity Index, Maximum Dry Density, Optimum Moisture Content, California Bearing Ratio (Soaked and Un-Soaked) at both 2.5mm and 5mm penetration by mixing soil sample with varying percentages of Propylene Fibers. Propylene Fibers were mixed with soil at varying contents of 0.5, 1, 1.5 and 2% of the dry weight of soil. The result suggests that on addition of propylene fibers, Maximum Dry Density (MDD) goes on decreasing and Optimum Moisture Content (OMC) goes on increasing. In addition to this, it has been observed from California Bearing Ratio (CBR) (Un-Soaked and Soaked) that for all samples values of 5mm penetration is higher than that at 2.5mm. In both Un-Soaked and Soaked at both penetrations (2.5 and 5) mm highest value is at natural soil.
