This article presents a study of random pavement roughness reproduction method in laboratory. At a certainty velocity, with Partial Wave Adding, road power spectral density (PSD) was reconstructed to obtain road surface roughness in time domain and this signal was therewith acted as the required recurrent target signal; then, white noise as input was used to identify the system frequency response function (FRF); finally, in order to satisfy the presumptive error precision, reiteration method was used to made test system's response approach target signal. The experiment example shows the validity of this method.
