Field Electrical Measurements for Bridge Deck Membrane Permeability and Reinforcing Steel Corrosion
The report discusses the problems associated with electrical resistance testing of bridge deck membranes for permeability and electrical potential testing of bridge decks for reinforcing steel corrosion. Obtaining an adequate electrical connection, or ground, to the deck reinforcing was found to be a major problem. Various methods of obtaining a good ground are discussed as well as ways to check the adequacy of a ground connection. Various aspects of the practical use of the electrical potential method as a working tool are discussed. It was found that the limits of undersurface fracturing in a bridge deck cannot be adequately determined by using only the electrical potential method. Also that deck potentials cannot be predicted with a reasonable degree of accuracy from soffit potentials. (Modified author abstract)
