AGING BRIDGES SAVED WITH MODERN CORROSION CONTROL METHODS
There is no question that bridges of metal can last a long time if cared for properly. Corrosion control is the key. Effective coatings applied to exposed metal surfaces guard against problems like pitting and rust that eventually ruin bridge structures. Coating selection will vary depending on several factors, including the chemical and physical properties of metal alloys used in bridge components. Most important, however, is probably local environment. Wet weather climates with frequent high humidity, snowfall and/or heavy rains are tough on metal structures. So are manmade corrosives like road salt and airborne pollutants. The article discusses case history examples of coatings developed to withstand such aggressive environments including neoparene elastomeric wrappings used in a suspension bridge cable rehabilitation project, painting systems, and hot-dip galvanizing.
