钢桥桥面沥青铺装层应变变化规律研究

Study on Variation of Strain in the Surfacing of Asphalt Mixture on the Steel Bridge Deck

在钢桥模型上进行SMA和AC沥青混合料铺装层直道疲劳试验 ,研究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。

Linear track fatigue testing on the surfacing of SMA and AC asphalt mixture is carried out in order to study on the rule of variation of strain and analyze the fatigue cracking of the surfacing of asphalt mixture on the steel deck plate.
