Literature Review on the Discrete Element Method in Asphalt Mixtures

Asphalt mixtures are commonly used in pavement engineering, especially for highway construction. The mechanism exploration and analysis of distress the main challenges researchers industry managers. Thereby, it is important to understand their properties interaction mechanisms asphalt mixtures. It difficult conduct some sophisticated or microscale tests laboratory, numerical simulation virtual can be solutions these cases with low costs. Discrete Element Method (DEM) a promising tool undertake tasks. This paper mainly summarized analyzed research progress development prospect DEMs from series technical sections. laboratory test results were often calibrate DEM simulations as well Two-dimensional (2D) Three-dimensional (3D) modeling. Several modeling methods developed generate digital samples, like user-defined, image-based, random-modeling. In addition, conclusions referenced by simulations.
