Accuracy evaluation of traffic speed coreless GPR techniques in pavement layer thickness estimation
Ground Penetrating Radar traffic speed surveys enable the collection of useful data about the condition of the road, in particular giving information about the thickness of pavement materials. Having a reliable and accurate method to "self calibrate" the GPR data, and thus avoiding the necessity to collect cores, would transform the GPR method into a fully traffic speed technique that provides a continuous measure of the layer thickness from post processed data significantly improving the efficiency of this method. In this work, layer thickness estimation obtained with two different self calibrating techniques and based on traffic speed data, have been compared with the real core values, in order to evaluate the accuracy of these "coreless" GPR methods.
