Abstract: Damages in flexible pavements are mostly due to weak soil subgrade. In this work, reinforced earth technique is used to improve the sub grade soil. It helps to improve the compaction characteristics of soil besides reduction in the permeability and compressibility. It also helps to increase its shear strength and the bearing capacity. Unsoaked CBR test are conducted on locally available soil reinforced with geotextile. Addition of geotextile results in reduction in the design thickness of flexible pavement. Then use of solid waste material of concrete recycled aggregates and natural aggregates at different combination as well as at different layers of flexile pavement. The software PLAXIS-2D are used to evaluate the performance of unreinforced and geotextile reinforced pavement. Traffic Benefit Ratio (TBR) arrived at indicates that addition of geotextile improves the service life of pavement.
