Abstract

Ultrasonic Surface Wave Methods are used to analyze impacts of small variations on different observables in a two-layer concrete medium. Rayleigh wave phase velocity derivative is proposed as a new observable and its behavior is analyzed and compared to classical observables qualitatively and quantitatively. A higher sensitivity of phase velocity derivative is observed and concrete slabs with various thicknesses and moduli are built to validate experimentally the numerical results.
