In this paper, GPR measurements, combined with deflection studies and extraction testing of asphaltic concrete cores were obtained at selected sites. The deviation between the GPR prediction and destructive coring was analyzed statistically. Using the cores location as objects and the results of extraction testing as attributes, cluster analysis was used to identify, if any, the attributes that affect the radar prediction of various types of flexible pavement. The paper partially demonstrates how GPR fits into the overall framework of pavement maintenance decisions and pitfalls associated with GPR in thickness predictions of fully and partially designed bituminous pavements.
