Sonic inspection techniques are currently being used for condition surveys to identify those bridge decks on which expenditures of funds are both necessary and cost effective. While the current sonic methods are reliable, they are too slow for the survey application. A need exists for a rapid, non-destructive method for assessing the general condition of the bridge decks without closing the deck to traffic. The inspection techniques considered for use were infrared thermography, electro-magnetic sounding, nuclear radiation and acoustic techniques. Electromagnetic sounding, by using pulsed radar, has the best potential for use in the development of a rapid survey system.
