裂缝是沥青路面最主要的一种破损形式。路面出现裂缝不但影响行车的舒适性和路容美观,而且极易扩展造成路面的结构性破坏,缩短路面的使用寿命。根据苏221线省道启东段公路沥青路面结构特点,通过对沥青路面裂缝裂缝部位现场钻取路面芯样的方式进行检测,结合当地的环境条件、行驶车辆情况等因素系统分析裂缝的成因,针对裂缝的不同成因,提出相应的处治对策。同时,总结裂缝处治技术,为以后的路面裂缝处治提供有效的治理手段。
Crack is the most important form of asphalt pavement damage. Cracks on the road not only affect the comfort of driving and beautiful road appearance, but also easily expand the structural damage caused by the pavement and shorten the service life of the pavement. According to the structural characteristics of Asphalt Pavement of Daqidong Highway in Su-221 Line, the cause of formation of cracks was systematically analyzed by means of on-the-spot drilling of pavement core samples on crack site of asphalt pavement, combining with local environmental conditions and traveling vehicles, Different causes of cracks, put forward corresponding treatment measures. At the same time, summarize the crack treatment technology, provide an effective control method for the future crack treatment.
