ABSTRACT:
Concrete bridge decks are waterproofed by first applying a primer over sound, dry and clean concrete which forms the bridge deck. A laminated membrane is then installed over the primed concrete surface, the membrane being comprised of reinforced cured and uncured elastomers. The membrane is then heated to the point where the uncured elastomer flows and rolled prior to cooling. A tack coat is then applied over the membrane and a wearing surface, such as asphalt, or the like, applied.
The membrane employed is comprised of an upper stratum of a cured elastomer, a reinforcing fabric such as woven fiberglass in the center thereof and a lower stratum of a soft, uncured, form stable elastomer adapted to flow on the application of heat.
