由于受材料、结构、气候及行车荷载等因素的影响,高速公路沥青路面会产生各种形式的裂缝,按开裂的形式可分为纵向裂缝和横向裂缝及网裂。裂缝不仅使沥青混凝土路面的品质下降,还会造成路面病害的恶性循环。如何防治沥青混凝土路面裂缝已成为预防性养护工作中的一项重要任务。根据作者的体会,施工前,要注意做好材料、设备和人员的准备工作;施工过程中,主要加强开槽灌缝和封缝2道工艺的质量控制。实际工作中,要不断创新常规的养护方法,选取合适的灌缝材料,改进裂缝的修补工艺,减缓了裂缝破坏的时间,延缓了病害的升级发展。 Due to the material, structure, climate and driving load and other factors, highway asphalt pavement will produce various forms of cracks, according to the form of cracking can be divided into longitudinal cracks and transverse cracks and net cracking. Cracks not only reduce the quality of asphalt concrete pavement, but also cause a vicious cycle of road disease. How to prevent and control asphalt pavement cracks has become an important task in preventive maintenance work. According to the author’s experience, prior to construction, attention should be paid to the preparation of materials, equipment and personnel. In the course of construction, the quality control of the two processes of slotted grouting and sealing should be strengthened. In actual work, we should continue to innovate the conventional curing methods, select the appropriate filling material, improve the repair process of cracks, slow down the time of crack damage, and delay the upgrading and development of the disease.
