摘要：AbstractThe paper employs multi-fractal theory to systematically research into appraising the road profile in order to overcome the shortages of the current used road roughness indices which cannot fine depict the characteristics of the road locally. The paper proves the road profile has the obvious multi-fractal characteristics. On this basis, multi-fractal spectrum and the parameters can be used in the research of the road profile. The results of road surface simulation results in each grades based on Fourier inverse transformation show there is no unique relation between multi-fractal spectral width and road roughness in different grades, while the vertical axis, intercept of the roads that have the same multi-fractal spectral width was different in Logarithmic distribution of measure and scale. Finally, the combination of multi-fractal spectral width and the IRI is proposed as supplement of current indices when necessary.
