Abstract
Aheated bridge deck (20) uses electrodes (24,26) embedded within conductive concrete and connected to a power Source to remove Snow and ice accumulation. A cement-based mixture containing optimal amounts of conductive materials is molded into pre-formed slabs (22) placed atop the paved Surface of a bridge deck. Alternatively, the conductive concrete may be cast in place on top of an existing bridge deck. A control unit with temperature and moisture Sensors may be coupled to the heated bridge deck.
