The axisymmetric finite element simulations through ANSYS software are carried out to evaluate the benefits of using geogrid in flexible pavements. This paper describes the behavior of asphalt concrete (AC) pavement under axisymmetric conditions and subjected to static loading. The results of flexible pavements improvement using geogrid are presented. Analytical results for four different most possibilities of geogrid reinforcement in the paved road layers have been evaluated. The optimum

Four types of reinforcing model and one type of unreinforced model of paved road were selected. The results showed that a higher tension stress absorption when the geogrid is placed between the base course layer and subbase layer in the selected model.
