车辙是沥青路面主要的破坏形式之一.过去很多研究表明摩尔库仑模型能够设计沥青混合料和分析在荷载作用下沥青路面行为.因此,基于摩尔库仑模型采用有限元软件模拟评价玻璃纤维格栅应用在沥青层面的性能,考察且评价了玻璃纤维格栅强度,沥青面层厚度和玻璃纤维格栅在沥青面层里的位置对沥青路面的抗车辙能力的影响.

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.
