“…An extended application of GPR is the localization of built-in reinforcement. For pavements, the elements in question include dowels and tie bars in jointed unreinforced concrete pavement (referred to as concrete pavement [9][10]). For bridges, the cover of reinforcement in bridge decks are evaluated more frequently [11][12][13][14][15][16].…”

The paper describes the current situation regarding the comparative measurement and accuracy of ground penetrating radars (GPR). GPR measurements are used for non-destructive diagnostic of roads and bridges, specifically for measuring pavement layer thickness and determining the location and position of reinforcement in concrete. The information used in the paper is based on the performed in-situ measurements. The conclusion includes recommendations of how to perform and evaluate the in-situ GPR comparative measurements.

“…GPR is commonly used as a diagnostic method for a variety of applications [5]. There are more or less sophisticated applications that focus on determining the rebar position and concrete cover thickness [6][7][8], some are trying to determine rebar diameter [8,9], or identify rebar corrosion in concrete structures [10]. Combinations of GPRs with other methods are also used to refine the measurement results, e.g., with electromagnetic induction [8], electrical resistivity [11], ultrasonic techniques [12] or to compare the possibilities of individual methods with each other [13].…”

It is important to use adequately reliable non-destructive methods that would be capable of determining the reinforcement conditions in concrete structures. Three different methods: ground penetrating radar, impact-echo method, and metal magnetic memory method were used for testing laboratory-prepared reinforced concrete beams (with a reinforcing bar of the same diameter along its whole length, reinforcing bar locally impaired, and reinforcing bar interrupted). The ground-penetrating radar proved the correlation of signal parameters with the reinforcing bar condition. An impairment/interruption reinforcing bar appeared in the record from measurements in the transversal and longitudinal direction by changes of the observed depth of the reinforcing bar from the concrete surface and direct wave attenuation. The impact-echo method proved that the shifts of the dominant frequencies from the response signal correspond with the impairment/interruption of the reinforcing bar. Results of diagnostics by the metal magnetic memory method were presented by a magnetogram of the magnetic field strength and field gradient on the measured distance. The changes in the magnetic field strength proved different stress concentration zones due to the reinforcing bar condition. The used non-destructive methods showed that they are capable of indicating the different reinforcement conditions in reinforced concrete beams. This paper indicates in which cases and for what reason it is appropriate to use these three methods and in what way they differ from each other.

This paper provides an overview of the existing literature on the subject of Ground-Penetrating Radar (GPR) methods for the investigation of reinforced concrete structures. An overview of the use of concrete and reinforced concrete in civil engineering infrastructures is given. A review of the main destructive and non-destructive testing (NDT) methods in the field is presented, and an increase in the use of GPR to reinforced concrete structures is highlighted. It was also observed that research in some application areas has been predominantly or exclusively carried out at a laboratory scale, and that similarly, other more application-oriented research has been developed only on real-life structures. The effectiveness of GPR in these areas is demonstrated. Furthermore, a case study is presented on a new methodological and data processing approach for the assessment of reinforced concrete structures using a high-frequency dual-polarised antenna system. Results have proven the advantages of using the proposed methodology and GPR system in order to improve the detectability of rebars, including secondary bottom lines of reinforcement. The horizontal polarisation was proven to be more stable compared to the vertical. Finally, it has been demonstrated that a more accurate location of the rebars in a high-density grid mesh arrangement can be obtained by means of data migration processing with a scan spacing of 5 cm and wave velocity information through the use of the hyperbola fitting method from at least the 30% of targets.
