Abstract

This paper summarizes the findings of modeling the micromechanical behavior of asphalt mastics and asphalt mixtures under various loading conditions. A commercial discrete element code called Particle Flow Code in 2-Dimensions (PFC2D) is used for this purpose. Asphalt mastics are simulated using an assembly of stiff particles randomly dispersed in a medium of soft particles, representing the aggregate fillers and the asphalt binder, respectively. The stiffening effect of the aggregate fillers on the micromechanical behavior of asphalt mastics is investigated at different filler volume fractions. These results are compared to Dynamic Shear Rheometer (DSR) measurements on actual mastics. These mastic models are used to simulate the micromechanical behavior of hot mix asphalt (HMA) concretes. The behavior of these HMA models was investigated at high and low temperatures under loading conditions similar to those applied in the Simple Performance Test (SPT) and the Indirect Tension Test (IDT), respectively.
