摘　　要：为研究钢桥面铺装中环氧沥青黏结层与浇注式沥青混合料铺装层配合使用时的黏结性能,采用拉拔试验研究了粉胶比、高温老化对环氧沥青黏结层黏结强度的影响,以及浸水、黏结层洒布量、黏结层与铺装层施工间隔时间对复合梁黏结强度的影响。试验结果显示,环氧沥青黏结层抗高温老化性能优良,加入矿粉会降低其黏结性能,复合结构的黏结层洒布量不宜低于0.6L/m2,施工间隔时间不宜大于48h。In order to study the bond performance of epoxy asphalt waterproof adhesive layer used with guss asphalt in steel bridge pavement, the pull-off test is used to study the influence of the ratio of filler and the high-temperature ageing on the bond strength of epoxy asphalt waterproof adhesive layer. And the pull-off test is also used to study the influence of soaking, the amount of the waterproof material and the construction interval between waterproof adhesive layer and guss asphalt layer on the bond strength of the composite structure. The results indicate that epoxy asphalt waterproof adhesive layer has good high temperature ageing resistance and adding fillers can reduce its bond strength. For the bond strength of the composite structure, the amount of the waterproof material should be more than 0.6 L/m2 and the construction interval should be less than 48 hours.
