Abstract:A detector was developed which maps the delaminated area of concrete on a bridge deck. It is an electronically controlled instrument which interprets acoustical signals taken from the concrete as the instrument cart rolls along the bridge. A prototype was constructed and conditioned for field service, Materials for surface treatment of concrete bridge decks were tested as deterrents to freeze-thaw scaling damage. The most effective materials were identified, and methods and schedules of applications were developed. Air entrained concrete was found to be the most resistant to freeze-thaw scaling, and a mixture of linseed oil and kerosene was found to be effective in combating freeze-thaw damage at a relatively low cost.
