摘要

The common practice of applying deicing salts on highway bridges increases the potential of reinforcing steel in these structures to experience extensive corrosion in the decks as well as the substructure. A new rehabilitation method which is believed to arrest the corrosion, restore structural integrity, extend the life, and provide interim safety until replacement at a later time is FRP jacketing. In line with this concept, all the columns of the Highland Drive Bridge at I-80 in Salt Lake City were rehabilitated with carbon FRP composites in June 2000. The present project will evaluate the performance of the carbon FRP composite for two of these columns and its ability to maintain a good bond to the concrete, thus restoring and maintaining the columns capacity after exposure to field conditions for eight years. In addition, the use of a GFRP spiral as a non-corroding column tie will be examined.
