| Abstract: | A dynamic analysis method in dealing with the FWD data is discussed. By a Fourier transform, the time domain FWD data is transformed to the frequency domain. Then the frequency response function is computed and discussed for the field data of a road section. It is verified that the method is effective to the dynamic analysis of the FWD data |
