近年来,随着我国经济水平的不断提高,在我国高速公路的使用过程中,通行量及通行时间都有较大幅度的提升。其中,沥青路面最容易出现的破坏形式则是不同类型的裂缝。按照裂缝出现的原因进行分析,其裂缝主要分为以下几种类型:路基沉降裂缝、半刚性基层的反射裂缝、沥青表层温缩型裂缝等等。相关施工单位应做好预防工作,在裂缝出现早期进行有效的处理,避免由于公路的承载力不足,造成路面的破坏速度加剧,使公路的使用能力降低。
In recent years, with the continuous improvement of the economic level of our country, the traffic volume and passage time have been greatly improved during the use of the expressway in our country. Among them, the most prone to asphalt pavement damage forms are different types of cracks. In accordance with the reasons for the emergence of cracks analysis, the cracks are divided into the following types: subsidence cracks in subgrade, semi-rigid base reflection cracks, asphalt surface shrinkage cracks and so on. Relevant construction units should do a good job of prevention work and deal with them effectively in the early stage of cracks so as to avoid the deterioration of the road surface due to lack of bearing capacity of the road and reduce the ability to use the road.
