Aesthetic Coatings for Concrete Bridge Components

The performance of aesthetic coating systems for concrete bridge applications was studied. Ten coating systems were selected and subjected to a battery of tests, including accelerated weathering, outdoor weathering, chloride ion penetration, and mechanical tests to assess their performance characteristics. Consideration was also given to surface preparation and application procedures, but common practices were determined to be adequate. The coatings evaluated consisted of acrylic, acrylic-siloxane, epoxy, and polyurethane materials. Aesthetically, the acrylic based systems exhibited the highest performance. However, these systems provided limited additional protection to the concrete substrate. The best overall performance was achieved by an acrylic-siloxane hybrid system utilizing varying proportions for the base and top coats. In this system, a primarily siloxane base coat provided improved chloride ion resistance, while a principally acrylic top coat produced superior aesthetics.
