Determination Variety of Pavement Layers Thickness by Using Ground Penetration Radar Technology


Ground penetrating radar (GPR) is a high-frequency electromagneticmethod commonly applied to a number of engineering problems especially in the transportation sector. GPR surveys are routinely and successfully used for quality assurance and quality control (QA/QC) verification in many Transportation Agencies of the world in last ten years. The present work is to apply the GPR technique for a selected roads sectors to measure variation of pavement layers thickness, (surface layer, base course) hot-mix asphalt (HMA) material, and granular subbase layer.
