Utilization of air-launched ground penetrating radar (GPR) for pavement condition assessment
HighlightsAir-launched GPR system is deployed to assess the condition of the pavement.The GPR signal reflection magnitude is a function of the presence of an interface.Dielectric properties of pavement is a function of the pavement material integrity.Pavement constituents and their volume fraction define the dielectric properties.The reflection amplitude is more a function of the nature of the layer interface.
AbstractGround penetrating radar (GPR) is an electromagnetic-based nondestructive geophysical tool that is widely used for pavement investigations, including the differentiation of pavement layers, the mapping of layer thicknesses, and the assessment of pavement condition. This paper presents a case study in which an air-launched GPR system consisting of two truck-mounted GSSI antennae driven at near-highway speeds was used to investigate two segments of asphalt paved roadway in central Missouri. The acquired data were interpreted; pavement layers were differentiated, the variable thicknesses of the pavement layers were mapped, bulk pavement condition were assessed, and optimum acquisition and processing parameters were developed. Core control, visual assessments, and limited ground-coupled GPR data were used to constrain and verify the reliability of the interpretations of the acquired air-launched GPR data.
