基于离散单元法的沥青混合料研究

摘要

In order to research and improve the traffic performance of the asphalt mixture,the paper regards the asphalt mixture as the coarse aggregate and the asphalt mortar,adopts the discrete element method to research the asphalt mixture,analyzes the internal stress changes of the asphalt mixture under the external impact,so as to provide the direction for the roadbed design of the asphalt mixture.%为了研究和改善沥青混合料的路用性能,将沥青混合料看作由粗集料和沥青胶浆组成的两相复合体,采用离散单元的方法,对沥青混合料进行了研究,分析了沥青混合料在外力作用下其内部的应力变化,为沥青混合料路面设计提供指导。
