Abstract

In this paper, TRUBAL based on Discrete Element Method (DEM) was modified to include the effects of asphalt binder between the granular aggregates. Viscoelastic (Burgers) elements were added in the normal and tangential directions between the particles. A Burgers element consists a Maxwell element (a spring and a dashpot in serial) and a Kelvin element (a spring and a dashpot in parallel) in serial. The pore-spring system was kept under quasi-static condition to limit the dominance of inertial forces and to reach numerical stability. Series of numerical tests were conducted under different loading combinations to simulate simple triaxial tests.
