摘要
采用贝雷法设计了SMA沥青混合料级配,并针对SMA"三多一少"的特点,修正了贝雷法中确定填料百分率的方法,进行混合料整体级配设计,经贝雷法设计的SMA混合料级配曲线与现行规范规定的级配范围进行对比,表明对于SMA,采用贝雷设计法与马歇尔体积设计是有差异的。
The paper designs the SMA asphalt mixture grading with Bailey method. In light of ＂three polys and one little＂ features of SMA, it modifies the filling mixture percentage determination method of Bailey method, carries out overall mixture grade design, compares the SMA mix- ture grading curve of Bailey method to modern grading scope, which shows that： as far as SMA being concerned, Bailey design method is different from Marshall volume design.
