Performance of Epoxy Coated Rebars in Bridge Decks
Epoxy coated rebar (ECR) was introduced in the mid 1970's as a means to minimize concrete deterioration caused by corrosion of the reinforcing steel and to extend the useful life of highway structures. This report summarizes the results of investigations performed by highway agencies in the United States and Canada, academia, and the Canadian Strategic Highway Research Program to evaluate the performance of ECT. A total of 92 bridge decks, two bridge barrier rails, and one noise barrier rail was evaluated in the States of California, Indiana, Kansas, Michigan, Minnesota, New York, Ohio, Pennsylvania, Virginia, West Virginia, and Wisconsin, and the provinces of Alberta, Nova Scotia, and Ontario. The overall condition of the bridge decks was considered to be good. Deck cracking did not appear to be corrosion related. Very few of the decks had any delaminations or spalls associated with the ECR. Any delaminations or spalls that were associated with corrosion of ECR were small and generally in isolated locations.
