Abstract:This report describes a 4-year bridge and test fence evaluation of protective coatings for maintaining weathering steel bridges. The test specimens consisted of steel panels cut from existing aged weathering steel bridges, along with some new mill scale bearing weathering steel as a control. The condition of the specimens ranged from extensively pitted and corroded (from chloride exposure) to mildly corroded and non-pitted. Specimens were cut from angle irons, stiffeners, cover plates, and web areas of bridges.
