摘要：	In the past two decades, micromechanical modeling has been recognized as one of the best approach in studying asphalt mixture. The micromechanical models have tremendous potential benefits in the field of asphalt technology, for reducing or eliminating costly tests to characterize asphalt-aggregate mixtures for the design and control of these materials. In this paper, a comprehensive review of the work done by a number of researchers is summarized, which includes some of earliest models such as the non-interacting particles (geometry not specified and geometry specified models), and the models with particle interaction, as well as the newly development models in recent years. This paper also describes the most recently de veloped Finite Element Network Model (FENM) and a clustered Discrete Element Model (DEM) used in micromechanical modeling of asphalt mixture. Demonstration of these models are provided, where virtual laboratory simulation and laboratory tests were employed. Other ad vances including the nanotechnology application in asphalt mixture is also briefly discussed.
