• Abstract:
  The Texas Department of Transportation uses ; precast prestressed concrete slab beam bridges for ; shorter-span bridges of approximately 30–50 ft in ; length. Conventional slab beam bridges have slab ; beams placed immediately adjacent to one another ; with a cast-in-place (CIP) topping slab. While these ; bridges are used extensively, they are more ; expensive than traditional prestressed I-beam ; structures on a per-square-foot basis. This project ; investigated the use of slab beams that are spread ; apart with precast concrete panel (PCP) stay-in-place ; forms between beams and a CIP concrete deck. ; Design guidelines have been developed for this ; alternate spread slab beam bridge system.
