超薄罩面在武罐高速“白改黑”中的应用研究

Research on application of ultra-thin overlays in “white to black” of WG expressway

结合兰海高速武罐段水泥路面进行“白改黑”路面改造工程实践,借助3D Move Analysis软件对直接加铺及设置应力吸收层的路面结构进行受力分析,研究“白改黑”路面结构力学响应,选择采用高黏度改性乳化沥青作为复合防水黏结层,改性超薄罩面作为抗滑磨耗层,确保了混凝土路面沥青铺装层的服务性能和抗滑能力。

Combining Lan-Hai high-speed Wuguan section of cement road surface reconstruction project, through 3 D Move Analysis software paving and set the stress absorbing layer directly on the stress analysis of the pavement structure of research “white to black” pavement structure mechanics response, choose high viscosity modified emulsified asphalt as composite waterproof bonding layer, modified ultra-thin surface as abrasion resistance, tshe service performance and skid resistance of asphalt pavement are ensured.
