抛丸处理桥面铺装工艺的应用

Application of Ball Blast Technique in Deck Paving Disposal

抛丸凿毛工艺能高效快速地清除水泥砼铺装层表面的浮浆,处理后的表面强度高、构造深度大,再结合优良的底涂层形成防水粘结体系,可以比较好地解决公路桥面铺装中沥青铺装层与水泥砼铺装层之间的粘结质量问题,从而大幅度延缓桥隧路面病害的出现,具有积极意义。

The ball blast and chiseling technique can clean the slurry on the cement concrete pavement surface with high speed and efficiency. The treated surface has high strength and structural depth. Combining it with good bottom coat to form a waterproof cementation system can solve the adhesive quality problem of asphalt pavement with cement concrete pavement in highway bridge paving effectively, thus the occurring of pavement diseases of highway bridge can be staved greatly. It is of positive significance.
