AC-20中面层多级嵌挤配合比设计过程及分析

AC-20 multi-grade stone-stone mixture design steps for the asphalt middle coat

以抗车辙能力作为中面层配合比设计评价的关键,按照体积嵌挤的原则对某高速沥青混凝土路面的中面层采用多级嵌挤方法进行设计,采用贝雷法参数进行评价,并对设计过程中的一些步骤进行分析。

Regarding rutting resistance as the key of the asphalt middle coat mixture design and according to the principle of volume,one highway asphalt concrete pavement is designed by ways of multi-grade stone-stone method.The gradation is evaluated by Bailey method parameter.Moreover,some steps of design are researched.
