The Characterization of Road Roughness on Bridge Decks and the Adjoining Pavement.

摘要

An investigation into the characterization of surface profile and roughness on bridges and the adjoining pavement has been made and the results are reported. This investigation included the decomposition of measured roughness on a wavelength basis,thereby making possible numerous comparisons and analyses of the components of roughness. In this report of the pilot study,several methods of characterizing and contrasting roughness types between bridge deck and the adjoining pavement are presented,along with limited results obtained from the analyses of three bridge projects.
