Rehabilitation of the Boivre Viaduct - A Multispan Prestressed Box Girder Bridge

摘要

style="text-align: left;">This paper describes the steps taken to rehabilitate a seven-span, 951 ft (290 m) long, continuous prestressed concrete box girder bridge, located about 180 miles (290 km) southwest of Paris, France.  Evaluation of the distressed structure was accomplished through both instrumentation and visual inspections over a 4-year period. The final corrective measures required the development of new materials and procedures along with a high level of quality assurance controls to ensure a successful project. The completed bridge resulted in a substantial savings of time and money.
