Title: PRECAST CONCRETE DECK MODULES FOR BRIDGE DECK RECONSTRUCTION
Abstract: Replacement of deteriorated and obsolete bridge decks is requiring increased attention from design and construction engineers. The need to shorten the time the bridge is closed to traffic has led to the use of precast concrete deck systems. Their value is demonstrated on bridges that must carry traffic for some portion of every 24-h period. Precast deck modules have been used on such diverse projects as expressway bridges in Pennsylvania and California and railroad bridges in British Columbia and Delaware. The Santa Fe Railroad has begun a multiyear program to replace timber decks with precast concrete on its 32 miles of bridges that have timber-deck and steel-girder designs. The precast deck modules used on these projects were produced at the site or produced at multipurpose plants and shipped to the bridge site. Placement was made with combinations of welded, epoxy, and cement-grouted connections. This paper reports on the state of the art of precast concrete deck replacements, their application in reconstruction, and their influence on deck design in new construction. (Author)
