Conductive Concrete
Traditionally, removing ice from pavement can be accomplished by a combination of several methods, such as plowing, natural melting, traffic movement, and chemical treatment. Because the bond between ice and pavement is strong, removal by plowing alone is not effective. Chemical treatment helps break the bond by melting into the ice and spreading under the ice layer. Most highway winter maintenance depends on using chemicals and fine granular particles as a primary means for deicing. However, using deicing chemicals and salt has caused damage to concrete and corrosion of reinforcing bars in concrete bridge decks which is partially responsible for the rapid deterioration of the transportation infrastructure in the U.S. ... < background continued >
