Abstract

The repetitive, high, and targeted stresses placed on pavements, whether bound or unbound, may hasten the ageing and collapse of the road structure. The main aim of the study is stabilization of subgrade using geosynthetics .Soil stabilization is a process of treating a soil to maintain, alter or improve the performance of the soil as a construction material and very importantly to minimize the cost of earthworks. In order to determine the preliminary and engineering (strength) testing of the samples, analysis were carried out. In this study, the results of studies on the performance of nonwoven geotextile within subgrade are carried out experimentally utilizing the California Bearing Ratio(CBR) testing arrangement.The experimental results give a clear indication that the presence of geotextiles increases the CBR value of the soil thus, geotextile should be employed as a modernized form of improving road construction on poor soils and to reduce the layer thickness of pavements
