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 bonding performance of epoxy asphalt bonding layer and pouring asphalt mixture pavement in steel bridge deck pavement, the pull-out test was used to study the bonding strength of epoxy asphalt bonding layer Influence, as well as the effect of immersion, the amount of adhesive layer sprinkling, bonding layer and pavement construction interval on the bond strength of composite beams. The test results show that the epoxy asphalt binder has excellent high-temperature aging resistance. The addition of slag will reduce the bonding performance. The bonding layer should not be less than 0.6L / m2 and the construction interval should not be longer than 48h.
