橡胶沥青防水黏结层施工工艺及黏结性能

Construction Technology and Bonding Performance of Rubber Asphalt Waterproof Cohesive Layer

鉴于我国因防水和黏结原因引起的桥面铺装层早期损坏日趋加重的局面,通过对桥面板处理及检测分析得知,采用抛丸处理方法能使界面达到使用要求;对橡胶沥青防水黏结层施工过程中的施工温度、洒布质量、养护等提出控制要求;结合室内和现场防水黏结层与桥面板的黏结力试验结果得出,二者具有较好的相关性。

In view of the serious situation of bridge pavement early damage caused by weak waterproof and cohesive force, the article processes and detects the quality of bridge panel, and get the result that us- ing blasting treatment method can achieve the requirements of interface. It proposes some control methods on construction temperature, spray quality, maintenance of rubber asphalt waterproof cohesive layer in construction. The result of indoor and field cohesion test of asphalt waterproof cohesive layer with bridge panel has good correlation.
