RECENT DEVELOPMENTS IN PRECASTING OF HIGHWAY BRIDGES AND STRUCTURES
THE IMPORTANCE OF PRECASTING IS EMPHASIZED IN BRIDGE CONSTRUCTION. TWO DIFFERENT SYSTEMS OF PRECASTING ARE DESCRIBED: (1) COMBINING PRECAST STRINGERS WITH CAST-IN- PLACE FLOOR SLABS RESULTING IN T BEAM SPANS, (2) THE FIELD ASSEMBLY OF PRECAST BEAMS OR STRINGERS AND FLOOR SLAB PANELS SEPARATELY WHICH ARE WELDED TOGETHER WITH CONCRETE TO FORM AN INTEGRAL STRUCTURE. EXAMPLES ARE GIVEN OF THESE TWO SYSTEMS. THE USE OF PRECAST MEMBERS IN CULVERTS AND TUNNEL LINING IS ALSO DISCUSSED. RECOMMENDATIONS REGARDING PRECASTING AND A DISCUSSION ON THE ADVANTAGES OF PRECASTING HIGHWAY BRIDGES AND STRUCTURES IS INCLUDED. EXPERIENCE IN PRECASTING BRIDGES HAS SHOWN THAT THE METHOD RESULTS IN SAVING OF TIME, LABOR, AND MONEY.
