摘　　要：对济南黄河一桥原桥面铺装病害类型及成因进行调查分析,提出了相应的养护方案和施工工艺,工程实践证明,采用橡胶粉改性沥青碎石封层具有良好的防水粘结性能,细级配的沥青胶砂和SMA-10沥青混合料既解决了水泥混凝土防水调平层取消后的找平问题,又保证了良好的密水性能,对提高铺装层整体的水稳定性能有利。The damage types and causes of the original deck pavement of Jinan Huanghe bridge are investigated and analyzed and the relative maintenance schemes and construction technique are put forward.The construction practice proves that the chip sealing of crumb rubber modified asphalt has good waterproof and cohesive performance,and fine grading asphalt mortar and SMA-10 asphalt mixture not only can solve the leveling problem after canceling the waterproof leveling course of cement concrete but also ensure the good water-tightness performance which is beneficial to improve the cement stability of overall pavement.
