Abstract:
Bridges that are candidates for rapid repair techniques have peak-hour traffic volumes that are so high it is not practical to close a lane to repair the deck or to install a deck protection system except during off-peak traffic periods. Results of the first 25 months of a 55-month project (Task 4 of Strategic Highway Research Program Project C103) to investigate rapid techniques for the protection, rehabilitation, and replacement of bridge decks are summarized. A review of the literature and responses to questionnaires sent to state departments of transportation (DOTs), Canadian provinces, selected turnpike and thruway authorities, technology transfer centers, and material suppliers was conducted. Techniques being used by the DOTs are identified and compared from the standpoint of frequency of use, performance characteristics, time demands, service life, maintenance, initial cost, and life cycle cost.
