High-temporal-frequency monitoring of transport infrastructure is crucial to facilitate maintenance and prevent major service disruption or structural failures. Ground-based non-destructive testing (NDT) methods have been successfully applied for decades, reaching very high standards data quality accuracy. However, routine campaigns long inspection times are required collection their implementation into reliable management systems (IMSs). On the other hand, satellite remote sensing...

Effective quality assurance and control inspections of new roads as well assessment remaining service-life existing assets is taking priority nowadays. Within this context, use ground penetrating radar (GPR) well-established in the field, although standards for a correct management datasets collected on are still missing. This paper reports signal processing method data acquired flexible pavements using GPR. To demonstrate viability method, dataset real-life pavement was used purposes. An...

In order to maintain the highest operational safety standards, it is crucial that surface and structural deformation caused by geophysical natural hazards human-related activities in linear transport networks (such as highways railways) are monitored evaluated. Today, Ground Penetrating Radar (GPR) a well-established technology among available non-destructive testing (NDT) methods for collection of ground-based information. Concurrently, space-borne Interferometric Synthetic Aperture (InSAR)...

Deformations monitoring in airport runways and the surrounding areas is crucial, especially cases of low-bearing capacity subgrades, such as clayey subgrade soils. An effective infrastructure asset allows to secure highest necessary standards terms operational safety requirements. Amongst emerging remote sensing techniques for transport infrastructures monitoring, Persistent Scatterers Interferometry (PSI) technique has proven evaluation ground deformations. However, its use certain...

Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) techniques are gaining momentum in the assessment and health monitoring of infrastructure assets. Amongst others, Persistent Scatterers Interferometry (PSI) technique has proven to be viable for long-term evaluation ground scatterers. However, its effectiveness as a routine tool certain critical application areas, such millimetre-scale differential displacements airport runways, is still debated. This research aims...

Bridge engineers increasingly prefer to use the Ground-Penetrating Radar (GPR) technique. GPR can yield data with very high spatial resolution, be acquired rapidly and even during traffic, causing low interferences. This paper presents a novel system that is designed developed for bridge applications. In addition it proposes new algorithm cracks tracking in three-dimensional domain. The effectiveness accuracy of procedure have been calibrated validated on four different bridges. this paper,...

Nowadays, severe meteorological events are always more frequent all over the world. This causes a strong impact on environment such as numerous landslides, especially in rural areas. Rural roads exposed to an increased risk for geotechnical instability. In meantime, financial resources maintenance certainly decreased due international crisis and other different domestic factors. this context, best allocation of funds becomes priority: efficiency effectiveness plans actions crucially...

Ground penetrating radar (GPR) is traditionally applied to smooth surfaces in which the assumption of half-space an adequate approximation that does not deviate much from reality. Nonetheless, using GPR for internal structure characterization tree trunks requires measurements on irregularly shaped closed curve. A typical hyperbola fitting has no physical meaning this new context since reflection patterns are strongly associated with shape trunk. Instead a clinical hyperbola, reflections give...

ABSTRACT The characterization of shallow soil moisture spatial variability at the large scale is a crucial issue in many research studies and fields application ranging from agriculture geology to civil environmental engineering. In this framework, work contributes area pavement engineering for preventing damages planning effective management. High variations subsurface water content can lead unexpected damage load‐bearing layers; accordingly, both safety operability roads become lower,...

ABSTRACT Clay content is one of the primary causes pavement damages, such as subgrade failures, cracks, and rutting, thereby playing a crucial role in road safety issues an indirect cause accidents. In this paper, several ground‐penetrating radar methods analysis techniques were used to nondestructively investigate electromagnetic behaviour sub‐asphalt compacted clayey layers soils unsaturated conditions. Typical materials employed for load‐bearing construction, classified A1, A2, A3 by...

Ash dieback, acute oak decline (AOD), and Xylella Fastidiosa are emerging infectious diseases (EIDs) that have spread rapidly in European forests during the last decade. Quarantine measurements mostly failed to repress outbreaks millions of trees already been infected. Identifying infected a nondestructive manner is high importance for monitoring, managing, preventing EIDs. The aim this article examine capabilities ground penetrating radar (GPR) on evaluating internal structure tree trunks...
