改性沥青玛蹄脂碎石混合料配合比设计

Mixture Design for Stone Matrix Asphalt with Modified Bitumen

根据沥青玛蹄脂碎石混合料（ＳＭＡ）的组成和特点，结合试验路的大量数据分析，逐步形成并提出了适用于南方高温、潮湿地区的改性沥青玛蹄脂碎石混合料级配组成设计方法．

A design method for stone matrix asphalt (SMA) with modified bitumen suitable to the southern high -tem- perature and wet area is presented in this paper, combining with the analyses for a large amount of datum on test roads and according to the composition and the characteristic for SMA.
