Three-Dimensional Microstructural-Based Discrete Element Viscoelastic Modeling of Creep Compliance Tests for Asphalt Mixtures

摘要: Microstructural-based discrete element (DE) models have been used for a better understanding of asphalt pavement concrete since the late 1990s. Most current studies done with two-dimensional (2D) models. Moreover, elastic are primarily employed simulation an matrix’s time-dependent behaviors. A 2D model is too simple to capture complex microstructure concrete, and not sufficient simulating viscoelastic Therefore, it necessary consider three-dimensional (3D) microstructural-based DE mixture Currently, easy build such 3D using existing techniques presented in previous studies. major challenge, however, reduce computation time run modeling process which extremely time-consuming. The primary objective this paper s...
