Investigation on Contact Force for Asphalt Mixture During Compaction Using DEM
Contact force for asphalt mixture has a significant effect on mechanical properties, and discrete element method (DEM) is a feasible and efficient numerical simulation approach to investigate on skeleton structure of asphalt mixture from microscopic perspective. A three-dimensional (3D) DEM compaction model which can well describe morphology characteristics of mineral aggregate, compaction temperature, was established to investigate the contact force. It indicates that aggregate–aggregate (A-A) merely exists in contact pressure force, aggregate–mortar (A-M) and mortar–mortar (M-M) exists in contact pressure force and tension force. While contact force of two-dimensional (2D) sections is employed to characterize the contact force of 3D specimens, it needs to investigate rationality of the selected section. The 3D DEM compaction model can be utilized to investigate contact force for asphalt mixture.
