Thin Polymer Overlays for Bridge Decks

2016-11-17  Proper application of a 2-lift thin polymer overlay on decks that are in good repair (no significant chloride contamination, corrosion and/or deck surface defects) have a life expectancy of seven to 15 years. The main advantage of thin polymer overlays is the long-term preservation of friction coefficients as the deck ages. Therefore, for applications where friction enhancements are needed, the thin polymer overlays are recommended unless deck conditions preclude it. If the purpose for the installation of the thin polymer overlay is to protect an uncontaminated deck against corrosion, a more cost effective approach may be to apply penetrating sealer instead shortly after construction, and repeating the sealer application every three to five years, depending on average daily traffic. On heavily-travelled roads, where routine reapplication can be particularly disruptive to traffic, the application of thin polymer overlays

Evaluation of Thin Polymer Overlays for Bridge Decks

Thin composite polymer overlays are a cost-effective method for extending the service life and serviceability of concrete bridge decks by filling concrete cracks and increasing skid resistance. The overlay is a thin (1/4 to 1/2 inch) layer of polymer that seals existing cracks and is embedded with aggregate for wear and skid resistance.
