Corrosion of steel-reinforced concrete bridges is a serious problem facing the WVDOT. This paper provides an overview of techniques for evaluating the condition of reinforced concrete bridge elements; methods for modeling the remaining service life and the service life extension provided by various repair and protection methods; and a review of the various repair and protection methods. Fick's 2nd Law of Diffusion, combined with Life-365 software, was determined the most reasonable method for service life modeling. Bridge element condition evaluation should be performed at routine intervals, depending on the condition and age of the structure being evaluated. Evaluations should use a variety of technologies and techniques, including half-cell potential measurements. This study concludes that the various types of repair, evaluation, and modeling techniques can be incorporated into any existing corrosion management through the development of a manual which outlines reliable, research-based procedures for assessing the condition of corrosion-deteriorated in-service highway bridges.
