Résumé / Abstract
This work investigates the friction-texture relationship: starting from a decomposition method of the pavement texture that is part of a new signal processing so called “Huang Hilbert Transformation” to texture parameters-friction relation. This method allows empirical decomposition of the texture profile to a set of basic profiles in a limited number, so called “Intrinsic Mode Functions” or IMF. From the obtained IMFs, a set of four new functions so called “Base Intrinsic Mode Functions” or BIMF is introduced and are characterized from the density and sharpness of the peaks contained in it. Then these two parameters are correlated with the pavement friction using different combinations. The above procedure is applied to a set of texture and friction data measured through test roads in France. The textures and frictions are measured using respectively the Circular Texture Meter (CTMeter) and the Dynamic Friction Tester (DFTester) in both countries. The obtained results show a good correlation between some of the BIMFs parameters (density and sharpness) to friction.
