خلاصه مقاله:

Geogrid reinforcement in a paved road in most cases will improve the performance of the transportation support. A series of two-dimensional finite element simulations are carried out to evaluate the benefits of integrating a high modulus geogrid in a paved road. This paper describes the behavior of reinforced asphalt concrete pavement under plane strain conditions and subjected to monotonic loading. Analytical results for three different most possibilities of geogrid reinforcement in the paved road layers have been evaluated. The optimum position was decided by the tension stress absorption value and deformation reduction rate. The results showed that tension stress absorption increases with shifting the geogrid towards the top of the pavement and attains the highest values when the geogrid is placed between the asphalt layer and base layer in the model.
