| 摘要： | This study presents the findings of a comprehensive assessment of conventional methods of condition evaluation and repair of concrete bridges. Case studies involving different techniques practiced in the US and Europe are presented in the report. The causes of deterioration of concrete are identified along with the methods of repair. The procedures for the recommended repair methods are outlined for the superstructure and substructure The repair procedures include: patching, deck patching, crack injection, overlays, sealers, expansion joint repair, repair of prestressed concrete bridge girders using longitudinal external post tensioning and metal sleeve splice, bearings, scour, abutments, footings and pier rehabilitation. |
