近年来,沥青路面的舒适性和安全性受到了反射裂缝问题的严重影响,雨雪侵蚀也在一定程度上加剧了路基稳定性的下降,使得沥青路面的使用寿命大大减短,成行车事故增多的原因之一。特别是加宽改造后,反射裂缝在温度变化下出现的问题尤为突出,因此目前迫切需要采取必要的防治技术来解决反射裂缝的问题。本文主要针对反射裂缝在加宽改造沥青路面中产生的原因,提出了几种防治反射裂缝的具体措施。
In recent years, the comfort and safety of asphalt pavement are seriously affected by the reflection cracking problem. Rain and snow erosion also aggravate the decline of roadbed stability to a certain extent, resulting in greatly shortening the service life of asphalt pavement and increasing the number of traffic accidents One of the reasons. Especially after the widening and reconstruction, the problems of reflection cracks under the temperature change are particularly prominent. Therefore, it is urgently necessary to adopt the necessary prevention and control technology to solve the problem of reflection cracks. This paper mainly focuses on the reasons why reflective cracks occur in widening and rebuilding asphalt pavement, and puts forward some concrete measures to prevent reflective cracking.
