SR 292 Over Perdido Keys – Challenges to Field Metalizing of Steel Superstructure

SR 292 Over Perdido Keys – Challenges to Field Metalizing of Steel Superstructure
Available for download

The Florida Department of Transportation (FDOT) undertook recoating of the superstructure steel components of the SR 292 high-level bridge over the Intracoastal Water Way (ICWW) in Perdido Key, Florida, which carries one lane of traffic in each direction and is the only connection between Perdido Key and the mainland. Due to the significant impact to businesses and the public, including tourists, from any proposed lane closures, FDOT looked for other means to address the deteriorating paint system, provide for a longer service life, and complete the work without any lane closures on the bridge.

Due to the significant impact to businesses and the public, including tourists, from any proposed lane closures, FDOT looked for other means to address the deteriorating paint system, provide for a longer service life, and complete the work without any lane closures on the bridge. This paper describes the project’s repair design and highlights the design issues, particularly the restrictions on having no lane closures and all work being completed from below deck; the design decision to use field metalizing on the superstructure steel components to reduce future maintenance needs and rehabilitation; replacement of deteriorated steel components; modifications to the FDOT specifications to address the metalizing work; and the decisions made during construction to allow for the timely completion of the project. The paper includes typical metalizing processes applied to the project to assure a successful installation.

One of the, if not the most, vexing problems for bridge maintenance personnel is the deterioration of bridge components below leaking joints. The joints may be open or closed, construction or expansion, but all seemingly leak shortly after construction or resealing. The bridge components affected by the leaking joints may be steel or concrete, but the end result is the same, deterioration.

 Silicone alkyds are single-component (1K) systems and do not require the mixing of components before application. These systems are easy for sailors to apply (via brush or roll), have an indefinite pot-life in a closed can, and will cure under harsh marine conditions, which are why these coatings have been utilized on the exterior topsides of Navy surface ships since the early 1960s. However, these “user friendly” coatings provide limited color and gloss retention, limited resistance to shipboard hydrocarbons, and limited resistance to staining from running rust and soot.
