The pavement undergoes premature failure much before their design life due to many reasons. The design of the pavement layers to be laid over sub grade soil starts off with the estimation of sub grade strength and the volume of traffic to be carried. The rutting and fatigue are considered to be the distress parameters in pavement design. The aim of the paper is to determine the stress developed in the pavement is based on the geogrid position of the pavement. In this study a geotextile (coir mesh) layer is added above the subgrade level as a reinforcement layer/separation layer to improve the stress distribution transferring to the subgrade and decrease the surface deformation, fatigue, rutting and cracking in pavement. The aim of this study is to overcome the rut and fatigue life of pavement after placing a geotextile coir layer over the subgrade in the pavement. In this work the ANSYS STRUCTURE SOFTWARE is used to evaluate (pavement strain) the effect of geotextile layer over the subgrade.
