Abstract:
This study, part of a larger national effort to research thin bonded overlays for bridge decks, investigated the relative performance and costs of various technologies used for thin overlays on concrete bridge decks. This element of the program considered four different overlay treatments applied to a total of 13 bridges along Interstate 90 in southwestern Montana. The overlay technologies considered consisted of two Portland cement related products, an acrylic polymer modified, cement-based topping (Thorotop HCR) and silica fume concrete; and two resin/aggregate systems, one with an epoxy binder (Flexolith 216) and one with a methyl methacrylate (MMA) binder (Degadur 330BD). Extensive documentation was collected on the pre-overlay condition of the decks, the overlay installation processes, the initial condition of the overlays, and the condition of the overlays after one or two winter(s) of service.
