The Cause and the Prevention and Cure of Waterproof Concrete Bridge Decking Pavement Layer Crack

桥面铺装层破坏而出现坑槽、裂缝、松散等病害是目前高速公路中最常见的病害,由于裂缝是引起材料破坏、断裂的根源。只有在弄清裂缝产生原因的基础上才能对症下药,进行科学设计、科学施工,预防裂缝的产生,从而提高铺装层的使用寿命。本文对防水混凝土桥面铺装层裂缝产生原因及防治作以简要分析。

at present, the disease of bridge pavement layer, such as pit and slot, crack, loosening, are familiar and prevalent in ex- pressway. The crack is the root of breading material breakdown and fracture, so we should be scientific in design and construct to pre- vent the crack to come forth, based on understanding the cause of crack. Through that, we can enhance the viability of pavement lay- er. This paper makes a brief analysis for the cause and the prevention and cure of bridge decking pavement layer crack.
