Repeated GPR Measurements Carried Out On a Test Field Facility

The repeated GPR measurements are carried out in order to investigate the internal changes in road construction after some time of usage. For this purpose, a test field constructed at the University of Žilina is used. The test field is investigated by GPR system with 2 GHz horn type antenna. Based on the survey, the best degradation model and prediction of future pavement degradation will be set. Two results of GPR investigation are presented in this article.
