Rutting is a major distress form found in asphalt pavements. Past research has shown that the Mohr-Coulomb model can be able to be applied for asphalt paving mix design and analyze the behavior of asphalt pavement under load. A series of finite element (FE) simulations are carried out to evaluate the performance of integrating a various modulus geogrid into the asphalt surfacing layer based on the Mohr-Coulomb model. The simulations are conducted under a parametric study to investigate the beneficial effects of geogrid reinforcement to the assistance of rutting, and to determine how much effects are influenced by the tension of geogrid and the thickness of asphalt surfacing layer as well as the placement of geogrid in the asphalt surfacing layer.
