Improvements to the application of ground penetrating radar and high resolution video to detect deteriorated areas of Portland cement concrete pavements were researched. Developments in radar technology and the interpretation of radar signals were studied as a means for detecting subsurface deterioration, while studies on video imaging were intended to provide a method for recording and cataloguing surface deterioration or distress. Advances in both technologies have made it possible to apply them as practical tools for sampling purposes. The research also provides a basis for further study to enhance the capabilities of both technologies and make them more suitable for project level decisions. Engineers and scientists interested in the two technologies and their applications for assessing the condition of concrete pavements will benefit from the research documented in this report.
