My project aims to investigate the influence of aggregate particle's morphological properties on asphalt mixture's porosity, stability and macro-texture, by means of an impluse-based Discrete Element numerical Method (iDEM) implemented in a Physics Engine (PE), combined with the algorithm based on mathematical derivation. Virtual particles with concavities of Limestone and Granite (from 20mm to dust) were created, and virtual skeleton of asphalt mixtures with mastic painting were reproduced. Porosity of asphalt mixtures can be predicted now. In the near future, stability and Mean Profile Depth (MPD) of macro-texture will also be predicted by the number of aggregate particles and volume of mastic of each asphalt mixture.
