钢桥桥面沥青铺装层直道试验研究

Research on Straight Track Test of Deck Asphalt Pavement Course of Steel Bridge

在钢桥模型上进行了 6种沥青混合料铺装层直道疲劳试验和高温车辙试验 ,研究了重复加载过程中应变变化规律 ,分析了桥面铺装层疲劳开裂性能 ,比较了各方案高温稳定性能。

Straight track fatigue tests and high temperature rutting tests of six schemes for asphalt mixture pavement course have been made on the steel bridge models. The regularity of strain change during the repeated loading has been studied, the fatigue cracking performance of steel deck pavement course has been analysed and the high temperature stability of every scheme has been compared.
