Evaluating the Performance of Georgia’s CRCPs Using Ground Penetrating Radar (GPR)

In an effort to provide reliable decisions regarding highway pavements, condition assessment is often conducted to evaluate pavement performance. For Continuously Reinforced Concrete Pavements (CRCP) evaluated in this study, pavement distress is classified as having transverse and longitudinal cracks and/or punchouts. This report evaluated the influence of reinforcement placement and concrete cover on distresses through the use of non-destructive testing methods that included Ground Penetrating Radar (GPR) and eddy current technology. In addition, this research evaluated whether an eddy current technology could be used in the absence of a cored sample for the calibration process of GPR in the field. Ultimately, information on pavement distress type and severity, reinforcement location, and cover depth was collected for six CRCP sites on major interstates in Georgia. This study confirmed that the location and depth of reinforcements affect the performance of CRCPs in terms of cluster cracking and punchouts.
