FOREWORD
Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly become a considerableeconomic burden to many State and local transportation agencies. Since the iron in the steel has a
natural tendency to revert eventually to its most stable oxide state, this problem will, unfortunately, still
be with us, but to a much lesser degree due to the use of various corrosion protection strategies
currently used in new construction. The adoption of corrosion protection measures in newconstruction,
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 variouscorrosion 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.

Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly be come a considerable economic burden to many

oxide state, this problem will, unfortunately, still be with us, but toa much lesser degree due to the use of various corrosion
