摘要
高速公路沥青路面在运营期间出现早期损坏现象,如开裂、泛油、剥落、车辙等现象,影响正常运营和路面美观、降低平整度,甚至会削弱路面的整体强度,缩短路面的使用寿命。本文分析了路面裂缝的原因和产生裂缝的机理,提出了高速公路路面裂缝的防治措施。
The premature failures harm of the semi-rigid type base asphalt pavements is very serious in the expressway,such as craze,floating oil,flaking and wheel tracking,etc.It will affect the road operation and appearance of road surface,reduce smoothness control of road surface,and more it will reduce the whole intensity and shorted life of road surface.The cause and mechanism of the road crack are aralyzed and the prevention and countermeasure are put forward in this paper.
