钢桥面浇注式沥青混合料铺装的性能

Performance of Guss Asphalt for Orthotropic Steel Deck Plate Surfacing

根据大跨径钢桥面铺装的使用性能要求,通过流动度试验、贯入量试验、车辙试验、低温极限弯曲试验、浸水马歇尔试验、冻融劈裂试验、间接拉伸疲劳试验等系统研究了浇注式沥青混合料的性能。与AC 13I及SMA的对比分析结果显示,浇注式沥青混合料在钢桥面铺装中应用比AC 13及SMA更有优势。

Based on the requirement for long-span bridge's orthotropic steel deck plate surfacing,the performance of guss asphalt as a candidate surfacing material has been reviewed,by liquidity test,penetration test,rut test,low temperature bending test,permeant Marshal Test,freeze-thaw split test,indirect tensile fatigue test.Compared with the test results of AC-13 and SMA,the guss asphalt has more advantages as surfacing of orthotropic steel deck plate of long-span bridge.
