目前,通常认为裂缝是沥青路面的主要缺陷之一,这是因为初期产生的裂缝对沥青路面的使用性能虽无明显影响,但随着表面雨(雪)水的侵入,导致裂缝处的路面结构层甚至附近的土基含水量加大,造成路面强度降低,在重行车荷载反复作用下,使路面产生结构性破坏,缩短了道路的使用寿命。在此通过裂缝产生的原因,探讨旧沥青路面、新建沥青路面裂缝的处理技术。
At present, cracks are generally considered as one of the major defects of asphalt pavement. The reason is that the initial cracking caused no effect on the serviceability of asphalt pavement. However, with the intrusion of surface rain (snow) water, the pavement structure Layer or even near the water content of soil-based increase, resulting in reduced road strength, heavy traffic load repeatedly under the road to produce structural damage and shorten the service life of the road. Here by the cause of cracks, to explore the old asphalt pavement, the new asphalt pavement crack processing technology.
