  • Abstract:
    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.
