水泥混凝土桥面铺装层水损害的成因及防治

Reasons for water damage in concrete bridge surface layer and prevention of it

针对水泥混凝土桥面的桥面沥青混凝土铺装中,由于压实度不足,在使用过程中极易出现水损害的现象,结合沿海高速公路射阳河桥面铺装的实际应用效果,提出桥面沥青混合料单独进行配合比设计,使沥青混合料具有易压实的特点,以适应桥面铺装的需要,保证铺装层的密实度。

Aiming at the problems that in the asphalt pavement process of concrete bridge surface, the water damage often appears caused by small intensity, the paper combining practical effect of bridge surface pavement in Sheyang river of coastal highway, proposes the methods of making the mixing proportion design of mixture for bridge surface asphalt individually, so as to make the mixture easy to be pressed, and thus meet the paving requirements and assure the intensity of paving layer.
