    Abstract

    The methodology developed in the accompanying paper is verified using Falling-Weight Def1ectometer (FWD) data from in-service highways. The procedure to transform Falling-Height Deflectometer data from the time domain to the frequency domain and its analysis In the frequency domain is presented. Frequency response curves based on back-calculated parameters obtained by other Independent methods, parameters identified using the proposed methodology, and the actual Falling-Weight Deflectometer data collected from the field, are compared to demonstrate the validity of the approach.
