摘要
基于Burgers流变模型,可以利用中心差分法建立并推导沥青结合料的离散元模型,并可使用二维颗粒流模拟程序(PFC2D)实现从数值上预估沥青结合料的流变特性。该模型和PFC2D预测结果的高可靠性均得到了充分的验证。
Based on Burgers model, a discrete element model of asphalt binders is established using the central-difference method, and the prediction for creep of asphalt binder using PFC2D is realized. Both the result of this model and PFC2D shows high reliability and precision.
