Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly become a considerable economic burden to many State and local transportation agencies. Because the iron in the steel has a natural tendency to revert eventually to its most stable oxide state, this problem will, unfortunately, still persist, but to a much lesser degree as a result of the use of various corrosion protection strategies currently used in new construction. The adoption of corrosion protection measures in new construction, such as the use of good design and construction practices, adequate concrete cover depth, low-permeability concrete, corrosion inhibitors, and coated reinforcing steel, is significantly reducing the occurrence of reinforcing steel corrosion in new bridges. This report summarizes the results of various research investigations in developing and evaluating the performance of various corrosion protection systems. This report describes materials and measures that can be used for corrosion control in reinforced and prestressed concrete bridge structures in new construction.
This report will be of interest to materials and bridge engineers, reinforced concrete corrosion specialists, and those concerned with the performance of reinforced and prestressed concrete bridges.
