Advances in micromechanical constitutive theories and modeling in asphalt mixture: A review

摘要

An overview of the micromechanical constitutive theories of asphalt mixture is presented in this paper. Studies about constitutive theories and modeling methods are grouped into different categories: models with non-interacting particles (with and without geometry specified), models with particle interaction, finite element network models (FENM), micromechanical finite element models (FEM), clustered discrete element models (DEM), disturbed state concept (DSC), numerical manifold methods (NMM), and meshfree manifold methods (MMM) used in micromechanical modeling of asphalt mixture. Advantages, limitations and perspectives of different micromechanical approaches for the simulation of asphalt mixture are also analyzed. It is concluded that DEM and FEM are effective methods for particle scale research of asphalt mixture. The needs for future research are discussed as well.
