近年来公路多使用水泥混凝土修筑而成,它高强度、较高水稳性和低维护支出的优点广受推崇,特别是像水资源丰富的江汉丘陵平原区域,其优点更是得以充分发挥,在公路表面水稳性上作用无可替代。但是,水泥混凝土修筑的公路也存在着无法避免的缺陷,如路面断板现象,而且更大的困扰是这种路面一旦破损后不容易恢复,直接影响公路的安全使用,导致设计使用年限无法达到,所以,必须想法提升水泥混凝土修筑的路面质量。现结合自身经验展开分析,希望能够弄清水泥混凝土路面断板的形成过程和如何有效预防。
In recent years, many roads are built with cement concrete, and its advantages of high strength, high water stability and low maintenance expenditure are widely respected. Especially in areas like Jianghan Hilly Plain where water resources are abundant, the advantages are even more exerted. Water stability on the road surface no substitute. However, there are unavoidable shortcomings on the roads built by cement concrete, such as the phenomenon of pavement breaking, and the bigger problem is that once the pavement is damaged, it will not be easily restored and will directly affect the safe use of the road. As a result, the design service life can not be achieved Therefore, we must think of ways to improve the quality of pavement constructed of cement concrete. Now combined with their own experience analysis, hoping to be able to clarify the formation of cement concrete pavement breaking process and how to effectively prevent.
