广东省高速公路沥青面层矿料级配设计探讨

Exploration on Guangdong Provincial Expressway Asphalt Surface Course Mineral Aggregate Gradation Design

论述了沥青面层混合料配合比设计的技术要求,根据当地的料源,设计了三种不同的矿料级配曲线,通过室内大量试验,对试验检测的各项技术指标比较,确定沥青面层矿料的最优级配曲线。

This paper discusses the technical requirements of asphalt surface course mixture design.According to sources of local materials, three different mineral aggregate grading curves are designed.Through extensive indoor testing of the asphalt mixture and various qualification contrast to determine the optimum asphalt surface aggregate grading curves.
