Corrosion Protection Systems for Construction and Rehabilitation of Reinforced Concrete Bridges

The corrosion of metallic structures has a significant impact on the United States economy. In a recent study, the total direct cost of corrosion was determined to be $276 billion per year, of which the costs a sizeable portion (16.4%) was associated with the infrastructure. The average annual direct cost of corrosion for highway bridges (including steel) was estimated to be $8.29 billion. Based on the annual cash outflows, the analysis shows that indirect (user) costs can exceed the direct cost by a factor of ten or more. This article presents details on various methodologies presently used for the rehabilitation of reinforced concrete bridges. In addition, the authors discuss the rationale for calculating the annual cost of corrosion. They also provide a brief synopsis on various corrosion protection systems being used for new construction.
