沥青路面开裂是路桥工程中无法避免的现象,无论路基是软性还是刚性的,沥青路面开裂都会出现其中。路面裂缝具有非常大的危害,最坏的结果是水分进入裂缝中,导致基层甚至路基软化,这样,路就会出现诸多的问题。比如说路面承载力下降,这就使路面的破坏大大的增加,导致多多事故的产生。所以,本文在探讨路桥工程中沥青路面裂缝产生的原因的基础上,给出了几点预防措施,为了能使沥青路面产生裂缝所造成的危害减少到最小。 Asphalt pavement cracking is an unavoidable phenomenon in road and bridge engineering. Whether the roadbed is soft or rigid, cracking of asphalt pavement will occur. Pavement cracks have a very large hazard, the worst result is the water into the cracks, leading to the grassroots or subgrade softening, so the road will be a lot of problems. For example, the bearing capacity of pavement is reduced, which greatly increases the destruction of the pavement, resulting in a lot of accidents. Therefore, based on the discussion of the causes of cracks in asphalt pavement in road and bridge engineering, this paper gives some preventive measures, and minimizes the damage caused by cracks in asphalt pavement.
