摘　　要：目前,多孔沥青混合料集料级配设计大多采用手工试算法或图解法,而且结果难以预测.以卡剖来集料堆积模型为基本算法,根据目标空隙率这一设计指标,用C++语言编程来设计多孔沥青砼的级配.计算的目标空隙率与实测空隙率间的误差较小,计算结果具有一定的可靠性,因此可以用来辅助设计多孔沥青混合料的集料级配.So far, manual calculation and illustration methods are always applied to working out the aggregate gradation of porous asphalt mixture. A program based on C ＋ ＋ is put forward as a new method,on the bases of Kapolyi model as principle and the target voids rate as designing index. It proves that the difference between the calculated target voids ratio and the practical voids ratio is indistinct and acceptable. It can be a substitute for the traditional methods.
