    Abstract

    The most important factor resulting from the investigation of the effects of road-surface texture characteristics on skid resistance is the technological consequences with a view to the composition of the wearing course. In the course of this work, qualitative data were obtained and evaluated, which shall later be supplemented by quantitative data, about the coefficient of friction measured with the locked wheel on the one hand and through tracings of the surfaces of cores and laboratory samples on the other hand. The tracings were carried out with a device that has a measuring accuracy of ±5 μm and a step length of 12.5 μm. To investigate the time-dependent changes of the road-surface texture under traffic, tests were carried out with a polishing simulator. Through the tracing of selected profiles and the statistical evaluation of the results before and after polishing, comparisons can be made with other existing systems for the measurement of the surface texture as well as prescriptions for new technological demands on materials for the construction of wearing courses. As a result of these investigations, the polishing test according to the British Standard Polished Stone Value (PSV) has been made obligatory for Austria.
