“…Other studies tried to simulate the rutting test of asphalt mixtures with 3D DEM and analyze the influence of internal structural characteristics of the mixtures on the rutting behavior (Zhang et al, 2018). The three-stage simulations (gravity drop, static, and rotary compaction) were performed on three different asphalt mixtures to analyze the internal consistency of the mixtures (Zhou et al, 2020). The randomly generated algorithm was used to establish a model to simulate the aggregate penetration test and the uniaxial creep test.…”

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