For many years, the bridge industry has struggled with structural designs that are conducive to corrosion because of limited accessibility during surface preparation and coating application activities. Examples of structural designs common to many bridges are back-to back angles and expansion joints. These surfaces, which are difficult to prepare and coat, continue to challenge facility owners, specification writers and painting contractors alike.

To address this industry challenge, the Authors have investigated the feasibility of preparing and coating the interior surfaces of back-to-back angles. The goal of the study was to develop a set of design parameters for surface preparation and coating application that can be employed when specifying corrosion protection of these types of designs.
