摘要
桥面调平层混凝土采用多碎石、低砂率的配比设计,表层骨料外露,仅覆盖很薄一层稀浆,提高了与沥青混凝土铺装层的结合力,提高了桥梁铺装层的耐久性。
The bridge leveling layer eoncrete mix is made of more stone and low rate of sand ratio ,the surface is exposed aggregate , covering only a very thin layer of slurry , enhance the binding force of the cement concrete layer and the asphalt concrete pavement, improve the durability of bridge paving layer.
