寒冷地区按密实原则设计沥青混合料

寒冷地区高速公路沥青路面经常出现一些不同程度的病害,如坑槽、裂缝、车辙、水损害、平整度差等早期破损现象。产生这些病害的主因素是沥青混合料不够密实,空隙率偏大。从车辙、密实度、裂缝、平整度等几个方面分析沥青混合料的底温路面性能,提出相应的防治措施。

Cold regions according to the principle of compacting asphalt mixture design

Cold region expressway asphalt pavement often appear some different degree disasters, like pot holes, cracks, ruts, water damage, poor early damage of smoothness. The virus that is the main factor of asphalt mixture is not dense enough, caused by large voids. From ruts, compactness, cracks, roughness, and so few on the temperature at the end of the road performance of asphalt mixture, propose appropriate prevention and control measures.
