浅议高等级公路沥青路面水损害及其预防措施

水损害作为高等级公路沥青路面早期破坏的主要原因之一,严重影响公路的使用性能,增加了养护成本。文章分析了沥青路面水损害的破坏机理及其形成的主要原因,并结合工程实际,从严格控制现场空隙率、减少离析现象的发生、合理选材三个方面提出了相应的预防措施。

Discussions on Water Damage and Preventive Measures of High-grade Highway Asphalt Pavement

As one of main masons for early damage of high-grade highway asphalt pavement,the water damage sedously affected the road performance and increased the maintenance costs.This article an-alyzed the failure mechanism of asphalt pavement water damage and the main reasons of its formation, and in combination with engineering practices, it proposed the corresponding preventive measures form the aspects of strictty controlling the field voidage, reducing the occurrence of segregation phenome-non, and reasonable material selection.
