REHABILITATION OF CRACKED ADJACENT CONCRETE BOX BEAM BRIDGES

Several of the older adjacent prestressed concrete box beam bridges in Delaware have developed significant longitudinal cracking on the beam soffit, in some cases resulting in exposed and even ruptured strands. The extensive deterioration has necessitated the replacement of one such bridge, and another is scheduled for replacement in early 1993. This paper presents results from an ongoing study aimed at determining the causes of the premature cracking and developing rehabilitation schemes for the beams. In particular, the use of composite plates as a means of rehabilitating the cracked beams is being studied.
