Nondestructive Testing of Reinforced Concrete Bridges using Radar Imaging Techniques;Final rept

摘要

The goal of this project was to examine the critical issues related to the use of GPR (ground penetrating radar) in the inspection of concrete bridge deck roadways. The research included: (1) the state of the assessment of GPR inspection of concrete roadways; (2) Numerical modeling of GPR interactions with concrete; (3) Laboratory tests of GPR interactions and inspection of concrete in 0.5 to 6 GHz range; (4) Field tests of GPR inspection of concrete including the use of a handheld system; (5) Recommended specifications for a field test system.
