摘　　要： 介绍了贝雷法级配设计的一些基本概念,评述了贝雷法在Superpave混合料设计中的应用,着重介绍了三参数级配控制法,结果表明经贝雷法设计的Superpave混合料既能抗车辙又能防渗水,是一种较好的级配设计方法。 Some basic conceptions of the Bailey method for aggregate gradation are briefly introduced here. The paper states the application of this method in the design of Superpave mixture, and primarily suggests using three ratios, [CA] Ratio, [FAc] Ratio and [FAf] Ratio, to control gradation. The result shows that the designed mixture has good rutting resistance and endurance. So Bailey method is a great one to design good asphalt mixture. There is one thing needs to be noticed. After controlling of aggregate gradation using the three parameters, please use the aggregate gradation to calculate the loose loaded density in reverse to modify the percentage.
