Investigating the use of GPR for pavement condition assessment
Over the last two decades, Ground Penetrating Radar (GPR) has become more and more present as a tool for the evaluation of asphalt pavements. Although it is mainly used for non-destructive determination of layers thickness, significant effort is invested in exploring its possible application in determining pavement distresses. The aim of research presented in this paper was to investigate possible application of GPR for pavement condition assessment. A visual inspection of pavement surface was carried out on heavily distressed, sporadically repaired local road. Map indicating type and extent of surface distresses was created. Upon visual inspections measurements were taken by two GSSI air-coupled antennas with central frequency of 1.0 GHz and 2.0 GHz. Simultaneously to GPR measurement, high resolution digital camera was used to record pavement surface distresses. GPR measurements were repeated on the same measurement line with different system parameters settings. Additionally positon of antennas was changed to collect data on both antennas in the same measurement line. Collected data was analysed in RADAN 6.6 software. Conducted surveys have partially enabled the determination of pavement surface as well as subsurface condition.
