文摘

Air-coupled antennas are more suitable for measuring layer continuity. Ground-coupled antennas had better signal to noise ratio and better resolution. LWD is more suitable for the evaluation of the surface layer. FWD is more appropriate for the structural evaluation of the overall pavement. NDT techniques combined proved to be a useful approach to access the subgrade.
