Evaluation of Highway Culvert Coating Performance
The objective of this study was to evaluate the performance of coatings for highway culverts and to recommend methods of improving culvert service life through improved coating systems and other means. A literature search was conducted through a review of technical literature and interviews with cognizant state officials throughout the United States. The literature search revealed durability problems with the most commonly used materials and coatings. Corrosion and erosion of interior surfaces appear to be the most serious durability problems in most states. Field investigations conducted in nine states confirmed the findings of the literature search. Most coatings exhibit durability problems under conditions of abrasive bed load and extreme corrosivity. Coating types examined at various test sites and actual drainage installations include: asphalt, asbestos bonded asphalt, asphalt paving, coal tar laminate, polyethylene, PVC, vinyl plastisol, aluminized, aluminum - zinc and epoxy coated concrete.
