DEM models of idealized asphalt mixtures

The stiffness behavior of an idealized asphalt mixture at the different air void levels was investigated in this paper. The asphalt mixture was modeled with the discrete element modeling (DEM) approach by randomly generated air voids in two dimensions (2D) and three dimensions (3D). Air voids were calculated within the DEM model to meet the specific air void level (i.e. 4%, and 10%). Sixteen di…

Two dimensional and three discrete element models for HMA

Hot Mix Asphalt (HMA) is a composite material that consists of mineral aggregates, asphalt binders and air voids. A Discrete Element Model (DEM) of the HMA microstructure was developed to study the stiffness behavior in both two dimensions (2D) and three dimensions (3D). Image analysis techniques were used to capture the HMA microstructure. The HMA microstructure was divided into two phases: ag…
