目前,我国公路、市政道路、厂区道路,大部分采用水泥混凝土路面。水泥混凝土路面,是以水泥浆为胶凝材料,以粗细骨料为强度刚架形成强度的一种高级路面。其具有刚度大、强度高、耐磨特性好、整体性与稳定性优等特点。但近来在使用中发现,由于一些路基通病引起了砼路面的破损,不仅影响了砼路面的美观、行车平稳和舒适性,而且不易修复,影响了水泥砼路面的使用寿命。在此结合实践经验总结了造成水泥混凝土路面破坏的因素,并探讨了一些控制措施。
At present, China’s roads, municipal roads, plant roads, most of the cement concrete pavement. Cement concrete pavement, cement slurry as a cementitious material, coarse and fine aggregate strength frame to form a high strength of the road. It has a large stiffness, high strength, good wear resistance, excellent overall and stability characteristics. Recently, however, it has been found that due to some common faults in the roadbed, concrete pavement is damaged, which not only affects the aesthetics, smooth running and comfort of the concrete pavement, but also does not easily repair and affects the service life of the cement concrete pavement. In this combination of practical experience summed up the factors that caused the destruction of cement concrete pavement, and discussed some control measures.
