浅谈沥青混凝土路面裂缝的原因及预防处理措施

Brief talk on the causes of cracks in asphalt concrete pavement and preventive measures

随着城市化进程的不断加快,城市道路的建设速度明显的跟不上时代发展的步伐。而沥青混凝土路面以其优越性在我国道路建设中得到了广泛的使用。但是,半刚性材料的主要缺点是,其抗变形能力不高,温度的变化会对其结构造成影响,当温度出现急剧变化时,就会产生裂缝,在沥青面层较单薄时,易形成反射裂缝等,从而导致路面被破坏,使用寿命缩短。本文在基于分析形成路面裂缝的基础上,提出针对性的优化建议。

With the acceleration of urbanization process, the construction speed of urban roads obviously lags behind the pace of the development of the times. The asphalt concrete pavement has been widely used in our country’s road construction because of its superiority. However, due to the poor deformation resistance of semi-rigid materials, cracks are prone to occur when the temperature changes significantly, and reflective cracks are prone to form when the asphalt surface is thin, resulting in pavement damage and shortened service life. Based on the analysis of the formation of pavement cracks, this paper puts forward targeted optimization proposals.
