RENEWAL OF TIMBER DECKS ON STEEL BRIDGES WITH EPOXY-BONDED PRESTRESSED-CONCRETE SLABS

Many of Santa Fe's aging steel girder bridges were converted to timber ballast decks in the 1920s. The ballasted-deck construction is highly desirable from a track maintenance standpoint but moisture retained in the deck causes steel corrosion and shortens paint life. The experimental program of renewing old timber decks with precast, prestressed concrete slabs bonded to the steel with epoxy grout was initiated to solve the problems. Transverse joints are epoxy bonded into a monolithic, water-tight deck. Lateral rigidity of the monolithic deck eliminated need to strengthen corroded lateral bracing and composite structure produced by bounding makes coverplate renewal unnecessary.
