Resonance tests of concrete structures have been successfully employed for structural integrity assessment of various concrete structures. However, the nature of resonance test limited its applications due to the significant time and efforts involved in coupling contact sensors to concrete surface. Recently, some researches have been performed to introduce microphones into impact-echo tests, one of resonance tests. In this paper, additional research has been carried out to make the microphone-based resonance tests optimal for concrete tracks. The research includes optimal measurement configuration for concrete tracks, and filtering scheme of acoustic signals in time-frequency domain for extracting stress wave components only. For validity and verification of the proposed testing scheme, field applications were made at a concrete slab.
