Study on Permanent Deformation Characteristics of Asphalt Pavement Based on Discrete Element Method

In this paper, the microscopic mechanism of rutting formation is studied by the Discrete Element Method (DEM). The particles in discontinuous asphalt mixtures are discretized into circular rigid particles by DEM, then the initial model is created in accordance with the actual pavement. The displacement vector changes of particles under loading and the process of rutting formation are presented in this paper. The asphalt pavement model has been built to simulate the material properties of asphalt pavement by the PFC2D software. At the same time, the displacement vector changes in each layer have been analyzed under loading. In addition, the mechanisms of permanent deformation have been studied and the rutting formation process of asphalt pavement has been simulated. The results show that the Discrete Element Method used to study permanent deformation characteristics of asphalt pavement is reasonable and feasible.
