水泥混凝土路面以其承载能力强、取材广泛和维护费用少等优点在我国公路建设中得到了持续发展。近年来,这类路面在早期均出现了不同程度的病害,其主要原因有:重载交通的增长,或因混凝土面板偏薄,或因板下基础缺乏稳定性,路面损坏严重,各地区大面积维修或改造已成为普遍现象。多锤头碎石化被用到路面维修施工中,产生了不小的经济效益。 Cement concrete pavement has been developed continuously in the highway construction of our country due to its advantages such as strong bearing capacity, wide range of drawing materials and little maintenance cost. In recent years, such pavements have suffered from various degrees of disease in the early stage. The main reasons are: the increase of heavy traffic or the serious damage to the pavement caused by the thin concrete slab or the lack of stability due to the slab foundation; Area maintenance or renovation has become a common phenomenon. Multi-hammer crushed stone was used in road maintenance construction, had no small economic benefits.
