2001 - USA - Development of Ground Penetrating Radar Signal Modeling and Implementation for Transportation Infrastructure Assessment

Paper by Amara Loulizi. Objectives: to determine the dielectric properties of concrete over the used GPR frequency range; to synthesize the reflected air-coupled radar signals and compare them with measured waveforms; to model and study the effects of simulated defects in concrete on the reflected air-coupled and ground-coupled radar signals; and to validate the research results in the field by predicting layer thicknesses of flexible pavements and detecting moisture in flexible pavement systems.
