All of particles complies with Gaussian distribution, meanwhile calculates particle numbers According to mass percentage, and selects parameter of particle and wall. The gradation of Bailey method about the maximum nominal particle diameter 16 mm is simulated by PFC2D, such as CA0.2, CA0.4, CA0.5, CA0.6, CA0.8. Determine moveability of asphalt mixture through rolling distance of accumulation particle it's when asphalt mixture is stable at the gravitation. Computer simulation result is identical to testing result.

首次采用PFC2D程序的线性接触刚度模型，选取颗粒和墙体参数，按设计质量的百分比换算成颗粒数量，按照高斯分布规律排列颗粒构成，对贝雷法设计的公称最大粒径为16mm的级配CA0.2、CA0.4、CA0.5、CA0.6、CA0.8进行堆积模拟，在重力作用下形成自然堆积，测定混合料基本稳定时的滚动距离来判断混合料的分离程度，得到结果与离析势能指数的测定结果完全一致。
