复合浇注式沥青混凝土高温性能分析

Study on High Temperature Stability of Composite Gussasphalt Concrete

由于钢桥面铺装存在特殊性,在国内浇注式沥青混凝土铺装并没有显示出更好的高温性能。本文采用高温车辙试验、贯入度试验等方法,分析了搅拌时间、预拌沥青碎石、结构厚度、改性剂及结构组成对复合浇注式沥青混凝土高温性能的影响,并提出了改善复合浇注式沥青混凝土高温性能的一系列措施。

For the particularity of the steel bridge deck pavement,in the domestic the gussasphalt concrete pavement did not show better high temperature performance. The impact of the mixing time,mixed asphalt macadam,the thickness of the structure,modifying agent and structure effects on the performance of composite gussasphalt concrete at high temperature was analyzed in this paper by the high temperature rutting test,penetration test method. And a series of measures were put forward to improve the performance of the composite gussasphalt concrete at high temperature.
