Discrete Element Modeling of Asphalt Concrete:

2018-12-10  A microfabric discrete element modeling (MDEM) approach is presented for modeling asphalt concrete microstructure. The technique is a straightforward extension of a traditional discrete element modeling (DEM) analysis, in which various material phases (e.g., aggregates, mastic) are modeled with clusters of very small, discrete elements.

2012-12-1  Highlight Element size effects were investigated on three-dimensional discrete element modeling of asphalt concrete. Mineral aggregate particles were simulated with the randomly created ellipsoids. Element sizes gave insignificant impacts on the predicted creep stiffness. Element size could affect time-steps, computational time, aggregate shape representations, etc. The keywords are as

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.

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 to ...
