THE DESCRIPTION OF ROAD SURFACE ROUGHNESS

It is shown that typical road surfaces may be considered as realizations of homogeneous and isotropic two-dimensional gaussian random processes. Complete description of any such process is provided by a single autocorrelation function evaluated from any longitudinal track, and a single direct spectral density function therefore provides a road surface description which is sufficient for multi-track vehicle response analysis. A new road classification method is proposed which is based on this function. /A/
