Abstract:
Practical experiences in the use of downward looking penetrating radar (radar) as applied to non-destructive evaluation (NDE) of masonry structures such as bridge decks, roadways and tunnels are described. Various configurations of radar and data presentation are considered along with theoretical operational concepts. Specific operational examples are cited including automatic signal analysis and processing. Discussion of void and other defect detection is included. The ability of radar to rapidly gather data while moving in traffic at speeds in the neighborhood of ten miles per hour is reviewed and its implications for pavement management systens are commented on. Case histories are presented.
