“…More recent applications were focused on the damage and water infiltration detection in order to analyze the bearing capacity of the pavements, highly affected by the water content underneath the asphalt [34,35]. They also include the detection of pavement layers [36][37][38], the analysis of material density [39], cracking analysis [40][41][42], water detection [43][44][45], and the analysis of drainage structures under pavements [46]. Other recent studies have analyzed the effect of moisture in GPR amplitudes and frequencies [47,48] or delamination [47,49].…”

“…GPR is also applied in the assessment of rigid pavements, with one of the main objectives being the identification of metal bars and layers thickness [54], and measuring the rebar cover depth [55]. The assessment to detect damage such as cracking and voids is another application in rigid pavements [41,42], [56]. These studies are mainly focused on the detection of damage areas, but in some cases the origin of the damage is also investigated, including the effect of roots in pavements [57] and the impact of weather and load conditions.…”

“…Several tests report that 1 GHz center frequency antenna [40,41], [65], or even larger frequency antennas [66], are valuable systems to characterize vertical pavement cracks. However, lower frequency antennas, for example 250 MHz, are in many cases more effective for detecting cracks because the larger wavelength is less affected by the heterogeneities and the aggregates grading of the layers [65].…”

The non-destructive testing and diagnosis of transport infrastructures is essential because of the need to protect these facilities for mobility, and for economic and social development. The effective and timely assessment of structural health conditions becomes crucial in order to assure the safety of the transportation system and time saver protocols, as well as to reduce excessive repair and maintenance costs. Ground penetrating radar (GPR) is one of the most recommended non-destructive methods for routine subsurface inspections. This paper focuses on the on-site use of GPR applied to transport infrastructures, namely pavements, railways, retaining walls, bridges and tunnels. The methodologies, advantages and disadvantages, along with up-to-date research results on GPR in infrastructure inspection are presented herein. Hence, through the review of the published literature, the potential of using GPR is demonstrated, while the main limitations of the method are discussed and some practical recommendations are made.

“…The first applications of GPR in pavement assessment were focused on the detection of layers, determining their thickness [31][32][33][34]. Later, the technique was applied to the detection of cracks [34][35][36][37] and to the analysis of properties and parameters of the asphalt and other layers, based on the estimation of their dielectric permittivity [38]. The method was also applied for moisture and infiltration control [39,40]).…”

“…Additionally, several studies demonstrate the ability of GPR to detect voids in pavements [55][56][57] and cracking [25,37]. In 2012, Saarenketo [56] developed a relationship that allowed the content of voids in a bituminous layer to be evaluated according to the average dielectric constant [58].…”

Ground Penetrating Radar (GPR) is a prospecting method frequently used in monitoring asphalt pavements, especially as an optimal complement to the defection test that is commonly used for determining the structural condition of the pavements. Its application is supported by studies that demonstrate the existence of a relationship between the parameters determined in GPR data (usually travel time and wave amplitude) and the preservation conditions of the structure. However, the analysis of frequencies is rarely applied in pavement assessment. Nevertheless, spectral analysis is widespread in other fields such as medicine or dynamic analysis, being one the most common analytical methods in wave processing through use of the Fourier transform. Nevertheless, spectral analysis has not been thoroughly applied and evaluated in GPR surveys, specifically in the field of pavement structures. This work is focused on analyzing the behavior of the GPR data spectra as a consequence of different problems affecting the pavement. The study focuses on the determination of areas with failures in bituminous pavement structures. Results epitomize the sensitivity of frequencies to the materials and, in some cases, to the damage.

Ground penetrating radar is a geophysical survey method widely applied to the assessment and monitoring of cultural heritage buildings. It is commonly used as a method of structural evaluation because it is nondestructive and noninvasive. This chapter describes the historical development of the method and explores the fundamentals and theory of ground penetrating radar systems and the properties of electromagnetic waves. Furthermore, it discusses some of the main applications and explains the procedure for data processing. Finally, it presents several case studies in the cultural heritage of Portugal and Spain.
