振荡压实在大跨径混凝土桥梁铺装中的应用

Application of Oscillatory Compaction Technology in Deck Pavement Construction of Long Span Concrete Bridge

由于大跨径混凝土桥梁桥面铺装层压实施工时,沥青混合料不易压实,且采用传统方法进行压实易对桥梁结构产生破坏:对振荡压实工艺在某大跨径水泥混凝土斜拉桥主桥铺装层施工中的应用情况进行介绍,经测试表明该工艺既可以避免施工荷载对桥梁结构的破坏,又可以保证铺装层沥青混合料具有较好的压实效果和路用性能。

During the construction of dech pavement of long span concrete bridge, it pact asphalt with higher viscosity, and the structure of bridge is prone to destruction s f much difficult to comtraditional compaction method is adopted. The working condition of oscillatory compaction technology used in the construction of deck pavement is introduced. With the results of tests, it is shown that this technology can not only avoid destroying the bridge structure, but also ensure the effect of compaction and road performance.
