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.
