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.

关键词: 多孔沥青砼, 卡剖来模型, 级配

Abstract: So far,manual calculation and illustration methods are always applied to working out the aggregate gradation of porous asphalt mixture.A prograMbased 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 diference between the calculated target voids ratio and the practical vows ratio is indistinct and acceptable.It can be a substitute for the traditional mmhods.

Key words: porous asphalt concrete, Kapo lyi model, gradation
