Rapid Detection Methods for Asphalt Pavement Thicknesses and Defects by a Vehicle-Mounted Ground Penetrating Radar (GPR) System

Abstract: The thickness estimation of the top surface layer and surface layer, as well as the detection of road defects, are of great importance to the quality conditions of asphalt pavement. Although ground penetrating radar (GPR) methods have been widely used in non-destructive detection of pavements, the thickness estimation of the thin top surface layer is still a difficult problem due to the limitations of GPR resolution and the similar permittivity of asphalt sub-layers. Besides, the detection of some road defects… Show more

“…Being capable of sensing discontinuity of electromagnetic properties in the ground, Ground Penetrating Radar (GPR) has been used as nondestructive remote sensing modality in many applications, including tree root detection [1], frozen layer monitoring [2], structural assessment [3], infrastructure inspection [4], and landmine detection [5][6][7][8][9]. However, GPR detection of Antipersonnel Mines (APMs) is always challenging because of clutter contamination, such as antenna coupling, ground reflection, and friendly objects (rocks, voids, etc.)…”

“…In recent years, ground penetrating radar (GPR), which allows for rapid and real-time measurements, has received great attention for nondestructive testing (NDT). This technique has been applied for pavement investigation [ 4 ], geological exploration [ 5 ], civil engineering [ 6 ], subsurface archaeological investigation [ 7 ] and thin-layer thickness estimation [ 8 ]. In the forestry field, GPR has provided an important method of root system architecture reconstruction [ 9 ], root diameter or biomass estimation [ 10 ], and moisture content [ 11 ].…”

“…In this case, the problem of their electromagnetic compatibility arises. This also complicates the use of so-called georadar lines for simultaneous scanning of the whole lane on the road [11,12]. Earlier, the authors presented a method of assessment the thickness of the road pavement layers, provided that the upper layer of the pavement has a small thickness (the optical path length in the material) [13].…”
