Current trends in non-destructive testing of reinforced concrete structures using GPR
Since about 20 years, Ground-Penetrating-Radar (GPR) has been applied for the inspection of reinforced concrete (rc) structures. Two-dimensional data acquisition, processing and interpre-tation were and are mainly used for obtaining structural information such as layer thicknesses or positions of fixtures, such as tendon ducts. Many of those applications are today considered as routine applications of the GPR method and are widely used in practice. In recent years, advanced GPR techniques such as 3-D data acquisition and processing, data fusion merging information from different antennas and inversion methods have been developed and implemented for the inspection of rc-structures. Also, material properties such as humidity or chloride content have been investigated in addition to the traditional study for structural information. This paper describes the main features of advanced inspection methods. Benefits and limits are discussed with the help of case studies.
