Abstract: Availability of sound road aggregates is rare and costly nowadays due to rapid growth in the pavement construction activity to meet the increasing demand due to infrastructure development. Construction of pavement requires large quantity of earth material. India is experiencing tremendous growth in infrastructure including road network and highways. 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. Use of plastic products such as polythene bags, bottles etc. is increasing day by day leading to various environmental concerns. Therefore the disposal of the plastic wastes without causing any ecological hazards has become a real challenge. Thus using plastic bottles as a soil stabilizer is an economical utilization since there is scarcity of good quality soil for embankments. Present research study focus on the evaluation of benefits of stabilization of subgrade soil. Construction of pavement requires large quantity of earth material. Waste plastics can be effectively utilized for improving the engineering properties of the weak soil. In present research was carried out to study the effect of plastic strips on Maximum Dry Density, Optimum Moisture Content, California Bearing Ratio and Standard Proctor Test by using 0.5%, 1%, 1.5% and 2% percentage of plastic waste by dry weight of soil.
Keywords: Maximum dry density, Optimum moisture content, California bearing ratio.
