| Very few studies have been attempted to understand the stress-strain behavior of flexible pavements reinforced with geosynthetics in the middle of asphalt layer. In this study, the flexible asphalt layer was analyzed with finite element method to understand stress-strain behavior. The asphalt layer was reinforced with glass grid and geogrid. The reinforcement was applied in the asphalt layer to prevent its excessive deformation and shear failure. The location of installation and stiffness of the geosynthetics were varied to obtain optimum depth of reinforcement and proper modulus. The results indicate that geosynthetics are more effective for reducing maximum shear stress than those of vertical stress and vertical displacement. Maximum shear stress decreased 15$sim$20%, and glass grid with high value of modulus was the most effective. Also, in order to prevent failure of asphalt layer, reinforcement should be installed in the 3cm$sim$5cm depth. |
