水泥混凝土路面是高等级公路路面结构的主要类型之一,自20世纪80年代以来在我国逐步得到推广。与沥青混凝土路面相比,水泥混凝土路面具有较高的抗压和抗弯拉强度以及抗磨耗性能。同时它也不存在沥青路面的“老化”现象,具有较好的稳定性。因其较高的强度和稳定性而经久耐用并且养护维修少。但其亦具有以下缺点,水泥和水的需求量大,因此在缺乏水源和水泥的地区很难推广。一般水泥混凝土路面由于自身特点而设置了接缝,这些接缝施工和养护困难、影响运营后行车的舒适性,如施工时对其处理不当将导致一系列的路面破坏问题。其开放交通比较晚,一般要等到28天后才能开放交通,且日后的养护维修工作比较困难、工作量大。
Cement concrete pavement is one of the main types of high-grade highway pavement structure and has been gradually popularized in our country since the 1980s. Compared with asphalt concrete pavement, cement concrete pavement has high compressive and flexural tensile strength and abrasion resistance. At the same time it does not exist asphalt road “aging ” phenomenon, with good stability. Because of its high strength and stability and durable maintenance and less maintenance. However, it also has the following disadvantages. The demand for cement and water is high, so it is difficult to popularize in areas where there is a lack of water and cement. Due to their own characteristics, ordinary cement concrete pavements have seams that are difficult to construct and maintain, which affects the comfort of vehicles after operation. Improper handling during construction can lead to a series of road damage problems. Its relatively open and open traffic, usually until 28 days after the opening of traffic, maintenance and repair work in the future more difficult and heavy workload.
