Evaluation of pavement condition by combination of FWD device and ground penetrating radar
 Stryk, Josef ; Březina, Ilja ; Matula, Radek ; Grošek, Jiří ; Janků, Michal
The combination of two non-destructive diagnostic devices – the Falling Weight Deflectometer (FWD) used to assess the bearing capacity of pavements and the Ground Penetrating Radar (GPR) used to determine the thickness of structural layers, to identify inhomogeneities, hidden defects and failures are increasingly being used in pavement diagnostics. The purpose of the methodology is to specify the procedure for performing measurements of combinations of these two devices, in the context of conducting a diagnostic survey of pavements. It draws attention to the benefits of processing data measured by both devices and their use in creating homogeneous sections, which serve as a basis for planning of maintenance, repair and reconstruction of roads. The presented methodology was prepared within project TE01020168 – Centre for Effective and Sustainable Transport Infrastructure (CESTI), with state support of the Czech Technology Agency within the Centre of Competence Program. This methodology is intended primarily for companies dealing with pavement diagnostic surveys
