• Abstract:
  The basic assumption in pavement design is that there is full support through out the length of the pavement. When a void developes, this is not true. This report investigates three methods of detecting voids underneath continuously reinforced concrete pavements. The methods; deflection, pumping, and vibration, are evaluated to find which has the highest probability of successfully detecting voids. The deflection method is shown to be very reliable in predicting voids beneath CRCP and as such a detailed procedure for void detection using this technique has been outlined. The successful detection of such voids, by the method outlined in this report can lead to the repair and subsequent restoration of pavements in which voids have developed. In this way, expensive major rehabilitation of pavements can be prevented.
