||Evaluation of Procedures for Coating Steel Components on Virginia Bridges
Stephen R. Sharp
This project will begin an in-depth study of conventional practices used by the Virginia Department of Transportation (VDOT) when it coats steel bridge components. Specific coating topics to be examined include: wet abrasive blasting; spot repair and overcoating; conversion coatings; surface preparation; and containment requirements.
The researchers will evaluate the performance of VDOT’s existing coated structures by reviewing current literature and historical data. The literature review and product search will determine candidate products VDOT should evaluate for future use. The literature review also will include an investigation of containment measures most suitable for various surface preparation and coating technologies from cost and environmental perspectives. In addtion, the team will collect information from VDOT and consultant inspectors, groups responsible for steel-coated structures and Virginia contractors certified by the Society for Protective Coatings.
