南方炎热地区重交通高速公路SMA配合比设计

结合广深高速公路沥青路面维修工程，探讨SMA在南方炎热地区重交通高速公路罩面维修工程中的应用及混合料配合比设计。针对地区与交通特点，在材料级配曲线的确定、马氏试件成型击实次数、水泥掺量、冻融劈裂试件击实次数等方面进行了有益的探索。

Design of SMA for Heavy Traffic Highway in Southern High-temperature Area

In this paper, the mix design and the application of SMA on resurfacing and maintenance of heavy traffic highway in southern high-temperature area were explored. According to the features of this area and the traffic, meaningful reseaches were made on determination of material grade curve, the cement content, and the beating times of specimens for marshall test and those for freezing and thawing test.
