Abstract
A heated bridge deck ( ) uses electrodes ( ) 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 ( ) 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.
