摘要
利用贝雷法,通过CA、FAc、FAf三个参数对ATB-40级配进行优化,对优化前后混合料的粗集料骨架、粉胶比、细集料填充等方面的路用性能进行了对比研究,阐述了贝雷法在优化ATB-40骨架型级配方面的应用情况。
The ATB-40 gradation is optimized by Bailey method through three parameters of CA, FAe and FAf. The pavement performance of coarse aggregate skeleton, powder binder ratio and fine aggregate filling before and after optimization were compared. The application of Bailey method in optimizing ATB-40 skeleton gradation is expounded.
