水泥混凝土路面裂缝是水泥混凝土路面常见病害,路面裂缝不仅影响路面工程质量外观,而且当裂缝宽度大于0.05毫米时,水泥混凝土路面结构的耐久性会受到一定的影响,因此必须对水泥混凝土路面出现的裂缝引起足够的重视。水泥混凝土路面裂缝分表面裂缝和贯穿裂缝,对于早期出现的裂缝,如果不进行及时修补的话,在自然因素和车辆荷载的反复作用下,水泥混凝土路面就会出现如面板开裂、局部坑洞、边角破损、接缝啃边等病害,对道路交通产生了一些不良影响,降低了行车安全性和舒适度,影响了道路美观,降低了使用寿命。目前我国工程中使用的水泥混凝土路面修补方法主要有扩缝灌浆法、条带罩面法、加筋维修法、压力注浆法、部分
Cement concrete pavement crack is a common disease of cement concrete pavement, pavement cracks not only affect the quality of pavement engineering appearance, and when the crack width is greater than 0.05 mm, the durability of cement concrete pavement structure will be affected to some extent, it must be cement concrete pavement Crack caused enough attention. Cracks on cement concrete surface cracks and cracks through, for the early cracks, if not promptly repaired, under the natural factors and vehicle loads repeatedly, the cement concrete pavement will appear such as panel cracking, local potholes, edge Corner damage, seams bite edge and other diseases, the road traffic has had some adverse effects, reducing driving safety and comfort, affecting the road appearance, reducing the service life. At present, China’s cement concrete pavement repair methods used in the main expansion grouting method, strip overlay method, reinforced repair method, pressure grouting method, part of
