USE OF PRESTRESSED, PRECAST CONCRETE PANELS IN HIGHWAY BRIDGE CONSTRUCTION

A beam and slab bridge that makes use of precast, prestressed panels was investigated. For this type of bridge, both the panels and the beams are precast and prestressed in the casting yard. In the bridge structure, the panels span the transverse distance between beams and serve as forms for the cast-in-place portion of the deck. They remain in place to become an integral part of the continuous structural slab. Composite action is obtained when the deck elements and the beams are bonded together by the cast-in-place concrete. Tests were made to determine the ability of this type of bridge to distribute wheel loads in a satisfactory manner and to behave as a composite unit. A full-scale, simple span, prestressed panel concrete bridge was constructed and structurally tested in the laboratory. The bridge was subjected to cyclic applications of design loads and finally to static failure loads. It performed satisfactorily under all load conditions. Several bridges of this type have been in service in Texas for 10 years and have performed well.
