水泥混凝土路面具有刚度大、强度高、稳定性好,使用寿命长等优点。同时,由于我国路用沥青受资源分布的限制,数量和质量均难以满足修筑路面的需求,而我国水泥产量大、分布广、各地均可就地供销。因此,公路水泥混凝土路面近几年发展迅速,特别是国家实施县际及县到乡镇公路建设工程,水泥混凝土路面被广泛采用。随着水泥混凝土路面建设的增多、通车里程的增加、使用年限的增长,路面相应出现了一些 Cement concrete pavement with rigidity, high strength, good stability, long service life and so on. At the same time, due to the limited resource distribution of road asphalt in our country, the quantity and quality of road asphalt are difficult to meet the needs of building pavements. However, China’s cement output is large and widely distributed, and localities can supply and sell goods locally. Therefore, highway cement concrete pavement has developed rapidly in recent years, especially in the implementation of national and county to township road construction projects, cement concrete pavement is widely used. With the increase of cement concrete pavement construction, traffic mileage increases, the use of the growth of life, the corresponding number of pavement
