Roca Spur Bridge: The Implementation of an Innovative Deicing Technology

Abstract

The heated deck of Roca Spur Bridge is the first implementation in the world using conductive concrete for deicing. Conductive concrete is a concrete mix containing a certain amount of electrically conductive components in a regular concrete matrix, designed to enable conduction of electricity. Due to its electrical resistance, conductive concrete can generate enough heat to prevent ice formation on a paved surface when connected to a power source.
