TLDR
In this article, the accuracy of pavement asphalt layer thicknesses estimation using ground penetrating radar (GPR) data analysis by employing different estimation approaches based on material dielectric properties is investigated.Abstract:
The Ground Penetrating Radar (GPR) is a Non-destructive Testing (NDT) technique, which is able to capture continuous pavement layer thicknesses data. The radar pulse propagation is a major factor for gathering the dielectric constants of pavement materials accurately. The present research focuses on the accuracy of pavement asphalt layer thicknesses estimation using GPR data analysis by employing different estimation approaches based on material dielectric properties. A comprehensive comparative analysis of GPR and asphalt-drilled cores data incorporating a variety of pavements is performed. The major findings of the detailed comparative analysis including the effectiveness of the approaches used are reported and discussed in the present paper.read more
