AN EVALUATION OF THE EFFECTIVENESS OF MEMBRANE WATERPROOFING FOR CONCRETE BRIDGE DECKS

The assessment is reported of the effectiveness of waterproofing membranes in Ohio (almost exclusively of the liquid-applied type) which involved the laboratory testing of most all membranes and the collection of data on all new field installations of both liquid and sheet membranes. The effect of construction practices was noted, and the use of a sand asphalt mix between the membrane and the surface course of asphaltic concrete was studied. Samples of membranes were made and tested for loss of impermeability by a modified version of the resistivity testing apparatus. The impermeability of membranes in the field was measured by a recently developed electrical resistivity method. Evaluatory comments are made on liquid-applied membrane systems such as Firestone and Goodyear, Marbilistic liquid neoprene, etc., and sheet membranes. Two built-up systems (a coal-tar emulsion with fiberglass reinforcing mesh and a Type B membrane) and a rubberized sand-asphalt system are also discussed.
