Corrosion protection of limited access areas common to bridge structural steel design

This study investigated the feasibility of preparing and coating various back-to-back angle widths and depths, and the performance of the applied maintenance coating system on the surfaces of limited access areas commonly found adjacent to bridges with structural steel design. The observed penetration of blast cleaning and coating application procedures to the areas inside the back-to-back angles that cannot be properly cleaned and coated is presented. The research was limited to the relative performance of a single maintenance coating system applied to 5 gap widths and 2 angle depths.
