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. Proctor’s compaction test, Unconfined compressive strength test, Unsoaked CBR and soaked CBR test are conducted on locally available soil reinforced with artificial fiber. Addition of artificial fiber results in reduction in the design thickness of flexible pavement. The software PLAXIS-2D and IITPAVE are used to evaluate the performance of unreinforced and artificial fiber reinforced pavement. Traffic Benefit Ratio (TBR) arrived at indicates that addition of artificial fibers improves the service life of pavement.
