Abstract
This paper Stabilization of soil using polypropylene fiber and fly ash is a study aimed to utilize waste products and optimize inclusion of these waste products in such a manner that maximum possible strength is imparted to soil being used in pavements, foundations etc. A varying percentage of polypropylene and optimized fly ash was used with soil for testing strength parameters using CBR and Direct Shear Test. With optimized flay ash, increase in percentage of polypropylene resulted in increase of CBR and Cohesion factor. In comparison to virgin soil (Clayey Sand – SC group) the soil mixed with 7%fly ash gave a substantial increment of 26.98% in CBR value. For soil mixed with 7%fly ash and polypropylene in varying percentages, a maximum 33.46% increment in CBR value was observed.
