Concrete Bridge Protection and Rehabilitation: Chemical and Physical Techniques. Rapid Concrete Bridge Deck Protection, Repair, and Rehabilitation

摘要

The report presents the rapid methods used by state highway agencies for the protection, repair and rehabilitation of bridge decks. The report is based on a review of the literature; the responses to questionnaires sent to state Departments of Transportation, Canadian provinces, selected turnpike and thruway authorities, technology transfer centers, and material suppliers; and the evaluation of 50 bridge decks located in seven states. Polymer overlays, sealers, high-early-strength hydraulic cement concrete overlays, and patches are compared for their performance characteristics and service life.
