DEVELOPMENT OF BRIDGE CORROSION COST MODEL FOR COATING MAINTENANCE

The authors of this paper address cost minimization of protective coating maintenance for steel bridges. Coating maintenance for steel bridges is critical and the problems, causes, remedial techniques, and associated costs to prevent corrosion are discussed. One of two analysis methods under consideration to limit the cost of coating maintenance for steel bridges is presented. The method, which is featured in the bridge corrosion cost model, uses equivalent annual costs to perform life-cycle cost analysis of three maintenance options: spot repair, overcoat, and recoat. The option that offers the minimum equivalent annual cost is considered to be optimal. A computer application that is 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.
