The ability of the SASW method in detection of layer thicknesses and moduli of multi-course pavements has been examined by numerical simulation of the test. The results are represented by the response of a pavement system to a vertical circular loading in the wave number and spatial domains, from which Rayleigh wave dispersion curves were derived using procedures equivalent to those in the field. The simulation shows that for common thicknesses and material properties of pavement surface layers, and the frequency range of accelerometers, the SASW method should enable detection of individual courses. The paper also discusses the influence of receiver positioning and an applied filtering criteria on the obtained dispersion curve.
