摘 要：通过对沥青玛蹄脂碎石混合料、多碎石沥青混凝土、密级配沥青混凝土进行的一系列路用性能试验研究，包括高温变形特性、水稳性、低温抗裂性、抗疲劳特性以及抗滑特性试验，结果表明沥青玛蹄脂碎石混合料具有优良的路用性能。

In terms of paving materials and erecting methods, the steel deck pavement systems adopted in the world can be generalized into four types:The first one is the Gussasphalt. Then is the Mastic Asphalt. Another one is the Stone Mastic Asphalt. And the last one is the Epoxy Asphalt.SMA has been widely applied in western countries such as European countries, Japan and America for its strong anti-track capability and well durability. It is still under experimental stage yet in China.
