INVESTIGATION OF A BRIDGE DECK REPLACEMENT SYSTEM FOR SHORT-SPAN BRIDGES

An experimental investigation was conducted to evaluate the durability and strength of a proposed bridge deck replacement system utilizing full-span prestressed concrete form panels. Two-full-scale specimens were fabricated and subjected to 5 million cycles of service loading before being loaded to failure. In addition, one specimen was subjected to 48 weeks of exposure cycling to determine the potential for delamination and assess the resistance to reinforcement corrosion. This study showed that satisfactory long-term performance can be achieved when composite action between the prestressed panels and CIP topping is ensured by applying a raked finish to the top surface of the panels.
