摘　　要：优良的防水黏结层是确保钢桥桥面使用耐久性的重要措施之一。通过对环氧沥青防水黏结材料的黏度、环氧沥青防水材料用量对粘结强度影响的试验,摊铺拖延时间的不同对防水黏结层性能影响试验以及常温下环氧沥青强度随时间变化试验研究钢桥用环氧沥青防水黏结材料的性能。试验研究结果表明:环氧沥青防水黏结材料的施工温度必须严格控制在13℃以上;最佳用量为0.8 L/m^2;高温季节面层摊铺需要在一周之内完成,普通情况下两周之内摊铺是可行的;在面层摊铺10 d之后才可以开放交通。Excellent waterproof bonding layer is one of the major measures to ensure the durability of Steel Bridge Deck.The performance of epoxy asphalt waterproof material for Steel Bridge Deck is studied by experiments on influence of epoxy asphalt viscosity and amount upon bonding strength,different delay paving time on property impact,and strength changing with time in normal temperature. The results indicate that the construction temperature of epoxy asphalt must be strictly controlled above 130℃,its optimal amount is 0.8L/m,the surface course paving should be finished in one week in hot season,and the paving can be done in two weeks in the ordinary situation,the road can be open to traffic after ten days.
