Soil Stabilization by Using Agricultural Plastic Waste

Abstract

Soil stabilization is a process which improves the physical properties of soil, such as increasing shear strength, bearing capacity etc. which can be done by use of controlled compaction or addition of suitable admixtures like cement, lime and waste materials like fly ash, phosphor gypsum etc. This new technique of soil stabilization can be effectively used to meet the challenges of society, to reduce the quantities of waste, producing useful material from non-useful waste materials. Plastic such as Pepci drip lateral is used to as a reinforcement to perform the CBR studies while mixing with soil for improving engineering performance of sub grade soil. Crushed plastic obtained from waste plastic were mixed randomly with the soil. A series of California Bearing Ratio (CBR) tests were carried out on randomly reinforced soil by varying percentage of crushed plastic with different proportions. Results of CBR tests demonstrated that inclusion of waste crushed plastic in soil with appropriate amounts improved strength and deformation behavior of sub grade soils substantially.
