摘要
A 4-channel, single-fold seismic acquisition system can be used to measure frequency domain response along paved roads. Shallow membrane delaminations and voiding defects are identified by a dominant mode consistent with membrane vibration and high-frequency attenuation above 100 Hz. The results correlate well with GPR profiles, and are especially useful for near-surface imaging where metallic clutter noise corrupts EM measurements.
