Bridge B-20-133 on US-151 With Fiber Reinforced Polymer Reinforced Concrete Deck;Final rept. (Nov 01- Oct 04)

摘要

In this research project the use of a new combination of Fiber Reinforced Polymer (FRP) composite materials to reinforce bridge decks was investigated. In the course of the research laboratory tests were conducted at the University of Wisconsin-Madison and a new bridge was constructed on US Highway 151 near the city of Waupun, Fond du Lac County, Wisconsin utilizing the innovative FRP reinforcing system. During construction quality assurance tests were performed on the FRP materials to ensure compliance with the special provisions, which had been developed for this project in collaboration with Alfred Benesch and Company. Constructed adjacent to this bridge was a nominally identical (except for 12 inch different in deck thickness) steel reinforced bridge to serve as a basis for comparison. FRP reinforcement provides a corrosion free alternative to traditional steel reinforcing. Utilizing FRP reinforcing will lengthen the service life of the bridge deck by avoiding the destructive cycle of concrete cracking, followed by corrosion of reinforcing, which in turn worsens cracking. The FRP reinforcing system also made use of stay-in-place deck panels, which reduce labor costs, construction time, and increase construction safety. Once construction was complete, load testing was carried out in collaboration with the University of Missouri-Rolla. The purpose of this research was to demonstrate the use of an innovative non-metallic, cost-effective, FRP reinforcing system for concrete bridge decks to a new bridge in the State of Wisconsin.
