采用冷铺超薄改性沥青修补受损桥面

Construction of Ultra-Thin Cold Modified Asphalt Bridge Pavement

介绍一种简单易行的受损桥面铺装技术。凭借SBS改性乳化沥青的优良性能,先设置防水层,然后采取稀浆封层的施工工艺加铺复合改性超薄沥青混合料作为桥面铺装。实践表明,这种桥面铺装使用效果良好。

A simple construction technique based on damage of concrete bridge deck pavement was introduced. With excellent performance of SBS modified emulsified asphalt, first waterproof course on bridge deck was laid with it. Ultra thin cold modified asphalt mixture as a bridge deck pavement was paved with slurry seal coat technology. The practice showed the effect of this bridge deck pavement was very good.
