Conductive Concrete Overlay For Bridge Deck Deicing, Sherif Yehia, Christopher Tuan
Christopher Y. Tuan
Concrete bridge decks are prone to ice accumulation. The use of road salts and chemicals for deicing is an effective method for ice removal, but causes damage to concrete and corrosion of reinforcing steel in concrete bridge decks. This problem is a major concern to transportation officials and public works due to rapid degradation of existing concrete pavements and bridge decks. The use of insulation materials for ice control and electric or thermal heating for deicing have been attempted and met limited success. Conductive concrete may be defined as a cementitious composite that contains a certain amount of electronically conductive …

Roca Spur Bridge: The Implementation Of An Innovative Deicing Technology, Christopher Tuan
Christopher Y. Tuan
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.
