Highway Research Report: Experimental Cathodic Protection of a Bridge Deck
An electrically conductive asphalt concrete was made by substituting coke breeze for the natural aggregate. By paving a bridge deck with the electrically conductive asphalt concrete, it was found that cathodic protection could be applied to the reinforcing steel. The cathodic protection was measured to be effective when corrosion of steel strips imbedded in concrete containing 10% calcium chloride by weight of the cement was stopped. As an experimental method of repair, two polymers and an epoxy were injected to bond the undersurface fractures. It was observed that the epoxy could be injected to effect a repair only under certain conditions. It is estimated that the cost of the cathodic protection installation was about $3.00 per square foot of deck ($32/sq.m.). (Modified author abstract)
