钢桥面铺装组合结构疲劳试验研究

摘要

桥面铺装是钢桥面行车体系的重要组成部分,桥面铺装质量的好坏直接影响行车的安全性和舒适性.针对"浇筑式沥青混凝土+环氧沥青混凝土"的钢桥面铺装方案,选择更易于引起铺装脱层及开裂的试验加我方法,分别对3种铺装组合结构进行疲劳试验,比较不同组合结构的性能,得出试验结论.试验结果时于大型钢桥面的组合铺装具有借鉴意义.%Deck pavement is an important part of vehicle driving system on steel deck, and the quality of deck pavement has direct impact on safety and comfort of driving. This paper, aiming at the steel deck pavement plan of “east asphalt concrete + epoxy asphalt concrete”, selects an test loading method easy to cause delaminations and cracks of pavement, carries out fatigue test for three combined structures respectively and compare performances of different combined structures, and draws test conclusions. The test results provide a reference for combined pavement of large - sized steel decks.
