Detection of Delamination and Cavities in Concrete
The objective of the study is a state-of-the-art report on available methods for the detection of delamination and cavities in concrete bridge decks and pavements. The decks and pavements are either exposed or have asphalt overlays. Four methods, i.e., the chain drag, the Delamtect, infrared thermography and radar were found to perform reasonably accurate delamination detection on exposed concrete decks and pavements. Of the four, only two, i.e. infrared thermography and radar, were found to perform well on asphalt overlaid decks and pavements. While the initial cost is high, infrared thermography and radar are cost effective when a large number of bridges and pavements need to be surveyed in a short period of time. This is often the situation in routine state production work.
