Description
Summary:This paper deals with minimizing the cost of protective coating maintenance for steel bridges. Coating maintenance for steel bridges is of major significance and is reviewed here in some detail with respect to problems, causes, remedial techniques, and associated costs. One of two analysis methods under investigation to minimize the cost of coating maintenance for steel bridges is presented in this paper. This first method, featured in the bridge corrosion cost model, performs a life-cycle cost analysis using equivalent annual costs to compare the three maintenance strategies: spot repair, overcoat, and recoat. The strategy that provides the minimum equivalent annual cost is considered to be optimal. A computer application, which will be presented in a later paper, has been developed to reduce the manual work required to implement the procedures described in the bridge corrosion cost model. Presentation of the second analysis method will follow in the near future.
