Research for AASHTO Standing Committee on Highways. Topic 48-03. Corrosion Protection for Extending Steel Bridge Service Life

Corrosion is one of the most often-cited problems with steel bridges. The need for a synthesis study on this topic is immediate. Owners are replacing a large number of Interstate Era bridges and building significant numbers of new bridges and transportation structures. Now is the time to choose materials, coatings, and details wisely and develop and implement effective long term care and maintenance plans for newly constructed bridges and transportation structures. Some of these approaches work better in different parts of the country; approaches that work well in northern states where deicing salts are a significant issue may not offer much benefit in coastal states where exposure to salt water and sea air are more of a concern. Making the wisest choice among the right coating, material, details and actions while considering the environment where the bridge will be located is complicated. While there has been much research performed in each of these areas, it has generally been done in a somewhat isolated and uncoordinated fashion. There is no single comprehensive document that provides both qualitative and quantitative information on all these various approaches. A synthesis is needed to compile knowledge on the various strategies and collect effective practices presently in use. Information will be gathered by literature review and a survey of the state departments of transportation (DOTs). Topics to be studied include research and practice on the following: (1) Coatings / surface treatments: (a) paint coatings; (b) galvanization; and (c) metallization. (2) Materials: (a) weathering steel ; (b) stainless steel, including ASTM A1010; and (c) standard structural steel. (3) Actions: (a) cleaning / washing; (b) recoating ; and (c) pot repairs of coating. The study will also identify gaps in knowledge and needed research. The payoff for this research will be multifold. This work may lead to reduced initial construction costs by illuminating cost-effective approaches for achieving corrosion resistance in steel bridges. This may also lead to reduced long term, life-cycle costs by educating owners about effective maintenance and repair actions. Further, this work may lead to reduced impacts on the traveling public by delivering bridges and transportation structures that are longer lasting and easier to maintain.
