| Abstract: | 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. |
