Title:

Anti-icing Overlay System: Progress Report #1, 2003-2004 Winter Season

Abstract:

This paper describes testing of an anti-icing technology that incorporates an epoxy and aggregate system that functions as an anti-icing overlay for concrete bridge decks or concrete pavement sections. The anti-icing overlay consists of a thin layer of epoxy spread over a bridge deck or pavement surface and a layer of an absorptive aggregate spread over the surface of the wet epoxy. After the epoxy has hardened, a liquid anti-icing material can be applied to the overlay surface and allowed to soak into the aggregate layer. The aggregate acts as a "sponge" to hold the anti-icing liquid near the surface and is slowly released back to the surface to act as an anti-icer preventing frost, ice or snow from bonding to the surface.
