摘要
沥青路面的早期病害已经成为影响道路服务水平的主要因素之一。文中结合山岭重丘区公路改造工程实践,针对沥青路面各种早期病害的特点,分别从外部因素和内部因素讨论了引起病害的机理。并针对各种病害的不同成因,提出了相应的防治措施,包括完善排水设施、优化配合比设计以及严控路面施工质量等。
The early diseases of asphalt pavement have become one of the main factors influencing the road service level.In this paper,the forming mechanisms by external and internal factors are dis-cussed according to the characteristics of different diseases based on the practices of reconstruction proj ects for mountain highways.In addition,according to different mechanisms,the corresponding treatment measures are presented,including improving drainage facilities,optimizing design of mix proportion,and controlling the quality of pavement construction.The forming mechanisms and the treatment measures could be referenced to other similar proj ects.
