Phase I GPR Study – Investigate use of GPR to Evaluate Type and Extent of Pavement Distress

This study will be a collaboration between Burns Cooley Dennis, Inc. (BCD) and Dynatest and have three primary objectives. Relative to the first objective, under SS 287 GPR traces were collected on each of the 64 test sections included in the SS 263 field sampling/testing project. SS 287 also evaluated the set of traces from each of 16 of the 64 test sections. The first objective in this proposed Phase I GPR study will be to evaluate the set of GPR traces that were collected from each of the remaining 48 test sections (64 - 16) to determine if additional potential distresses can be identified. The second primary objective will be to identify a limited number of sections for further investigation in the field via coring to substantiate the hypothesis that anomalies observed within GPR traces can be used to identify distresses present within a pavement structure. Based upon the GPR trace evaluations for each of the 64 test sections, select location(s) within a small subset of the 64 test sections will be cored to prove/disprove the observed GPR anomalies. The final objective will be to recommend whether to conduct a Phase II study which would involve coring GPR anomalies observed within the remaining test sections not cored in phase I. It is envisioned that field coring in both phases would provide sufficient correlation of observed anomalies within GPR traces to pavement distresses to establish reliability in use of GPR as an aid in developing pavement maintenance and rehabilitation projects.
