The thesis deals with road skid resistance, and with the possibility to predict its evolution through laboratory tests and models. First an original laboratory method is presented to polish and to measure the friction coefficient, using the Wehner & Schulze machine, developed in Germany. This method allows the measurement of friction coefficient vs. polishing time. Road sites are monitored to compare laboratory results with actual skid resistance. In parallel with experiments, mathematical models are built. A 5-parameter best fit model is first proposed, some parameters of which are related with aggregate characteristics, such as PSV, maximum size and microtexture. Then, a more physical model is described, which separates the three main mec...
