“…This is more evident in rural environment where roads, railways and runways can typically generate numerous PSs. Several applications of PSI related to the transport infrastructure monitoring can be found in the literature, such as [8][9][10][11][12][13][14][15], confirming its applicability to this area of endeavour.…”

“…Benefits of this integrated approach is demonstrated by several past research applications [106], [118], [119] that have demonstrated the effectiveness of the coupled use of the InSAR technology and GPR method. The findings from these studies suggest that the integrated approach can correctly characterise the railway ballast deterioration.…”

“…Test outcomes prove the viability of the proposed methodology for monitoring the health of transport assets at network level. Moreover, same authors [119] have employed the integration of the GPR and the Interferometric InSAR techniques for the monitoring of the rail-abutment transition area in railway bridges. On one hand, GPR was used to obtain structural details of the subsurface (thickness of the ballasted layer, position of the sleepers, presence of clay/humidity spots) and to identify potential construction-related issues.…”

Health monitoring of ballast in railway infrastructures is crucial to assure structural stability and efficiency of the operations. To this extent, an efficient and sustainable management of maintenance is fundamental for asset managers in setting up strategic and effective action plans. Amongst the available methods to assess the conditions of railway infrastructures, non-destructive technologies (NDT) are gaining popularity due to their capability to overcome main drawbacks of traditional routine methods, such as digging trenches and visually inspect locations assumed as critical along the track. The present paper presents an overview of the use of the Ground Penetrating Radar (GPR) and the Interferometric Synthetic Aperture (InSAR) technologies for a sustainable monitoring of railway infrastructures. Specifically, main traditional and non-destructive methods used for maintenance of railway ballast materials are presented with a special focus on their sustainability. A review about the research methods on the use of GPR and InSAR technologies for railway infrastructures also reported, including main investigations carried out in the laboratory and the real-life environments. Furthermore, a conceptual framework based on an integrated approach including satellite-based and ground-based investigations is proposed, where network and local level information can be merged for the detection of critical sections and the implementation of a more advanced predictive maintenance system.

“…The use of a multi-temporal InSAR (interferometric synthetic aperture radar) for transport infrastructure monitoring has also been significantly increasing during the last few years [294][295][296]. Studies undertaken on railways have shown the potential of the applicability of In-SAR together with GPR, mainly for the detection of causes of track subsidence [297], and to monitor subsidence at the transition zones of railway bridges [298]. It is important to highlight the relevance of the GPR, which can be synergistically used with other NDT to validate the results obtained by InSAR and to identify the possible causes of the displacements detected.…”

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.
