水泥混凝土桥面耐久性铺装结构研究

Durable concrete bridge deck pavement structures research

针对不同桥型,设计了六种不同的耐久性水泥混凝土桥面铺装方案,通过复合结构疲劳试验和动态蠕变试验,对所提出的铺装方案的耐久性进行了综合比较与经济性评价,推荐了适用于不同桥型水泥混凝土桥面的铺装方案。

According to different size of bridge, six kinds of durable concrete pavement structures were raised in this paper. Through the fatigue test and dynamic creep test on composite structures, we made comprehensive comparative analysis and conducted economic evaluation on the six proposed pavement structures. We recommended structures for deck pavement of concrete bridge in different length.
