摘　　要：在沥青发泡腔结构研究中,利用Fluent仿真沥青发泡过程,将仿真结果与试验值对比;并利用Fluent仿真结果中的出口平均速度和出口平均密度两个指标间接评价沥青发泡效果和沥青发泡腔结构的优劣。结果表明,该方法能够缩短施工设计周期,减少试验次数,节省人力和资源。In the study of the structure of asphalt foaming cavity, the process of asphalt foaming was simulat-ed by using the Fluent software, and the simulation results were compared with the experimental values. The effect of asphalt foaming was evaluated indirectly by using two indices of the average export velocity and densi-ty, so as to assess the merits or defects of the structure of asphalt foaming cavity. The results show that this method can shorten the design cycle time, reduce the number of trials and save manpower and resources.
