Stiffness evaluation of trackbed has been challenges to practitioners trying to seek for solutions to mud-pumping problems, train-induced vibrations, and etc. It is also related with structural integrity issue of concrete track overlying trackbed. In this paper, a new method called beamforming technique which utilizes surface wave inversion for stiffness evaluation of trackbed is proposed. Love waves were introduced in addition to Rayleigh waves to make a better characterization of the area with localized material. Extending the beamforming technique with the use of Love waves turns out to be a significant improvement in accuracy and reliability. For verification, field investigation has been made at the transition zone and is presented in this paper.
