Abstract This paper investigated effects of element sizes in three-dimensional discrete element modeling of asphalt concrete. Asphalt concrete was considered as a two-phase composite of mineral aggregates larger than 2.36 mm and asphalt mastic. Even though asphalt mastic was a composite of fines, fine aggregates, asphalt, and air voids in the reality, it was considered as a homogenous media

Discrete Element Modelling of Idealised Asphalt Mixture

and modelling the deformation behaviour of asphalt mixtures. With the Discrete Element Method (DEM), it is possible to model materials that consist of individual particles where a particle may roll or slide relative to other particles. The DEM offers a means of gaining an insight into the micromechanics of the deformation process.
