PRECAST CONCRETE SEGMENTAL BRIDGE IN TEXAS

LONGER SPANS ARE DESIRABLE FROM CONSIDERATIONS OF (1) ECONOMY, (2) SAFETY, AND (3) AESTHETICS. A SEGMENTAL CONCRETE STRUCTURE IS CONSIDERED IDEAL FOR THE PARK ROAD 22 BRIDGE IN TEXAS BECAUSE OF THE EXTREMELY CORROSIVE ENVIRONMENT AND THE NAVIGATIONAL CLEARANCE REQUIREMENTS NECESSARY FOR A STRUCTURE 3,280 FT LONG WITH 400 FT CONTINUOUS SPAN OVER AN INTRACOASTAL WATERWAY. THE FINAL DESIGN FOR THE SEGMENTAL STRUCTURE REQUIRES TWO SINGLE-ALE BOXES JOINED WITH A 2 FT CAST-IN-PLACE LONGITUDINAL JOINT. THE SEGMENTS ARE TO BE ASSEMBLED IN BALANCED CANTILEVERS AND THE PROPOSED PROCEDURES ARE GIVEN. A 1/6 SCALE MICROCONCRETE MODEL IS BEING CONSTRUCTED TO STUDY THIS DESIGN UNDER CONTROLLED LOADING, TO PINPOINT THE PROBLEMS, AND SERVE AS A TRAINING AID.
