摘要

The use of impulse radar to distinguish between areas of good bridge deck and areas which suffer from one or more different forms of deterioration, including delamination, scaling, and debonding, is reported. The radar signal is also used to measure the thickness of asphalt and concrete cover over reinforcement. These quantities are important in determining the amount of material to be removed when resurfacing a bridge deck. The calibration procedure and interpretation of radar waveforms are discussed in detail.
