摘要
In order to analyze the mechanical properties of asphalt mixture comprehensively and find out the mechanical response of asphalt mixture, a methodology of finite element multiscale model was proposed. By analyzing the characteristics and phenomenon of asphalt mixture occurred in the small scales, and combining meso-mechanics method with macro-mechanics method, the mechanical property of asphalt mixture, including the damage evolution process was simulated. Thus, it can implement coincident deformation among different scale models. Results show that the model can qualitatively simulate the mechanical property of asphalt mixture. It also can be used to analyze different components and evaluate property of asphalt mixture.
