CONSIDERATION OF THE QUESTION OF SKID RESISTANCE OF CARRIAGEWAY SURFACES, PARTICULARLY OF CONCRETE

BETRACHTUNGEN ZUR FRAGE DER "GRIFFIGKEIT" VON FAHRBAHNDECKEN UND VON BETONBELAEGEN IM BESONDEREN

Starting with a survey of the state of knowledge of the subject of friction between tyres and carriageway, the multiple influence characteristics of frictional contact are discussed. From this it follows that the degree of "operational safety" of a particular section of road should have accident occurrence alone as the determining quantity and not the coefficient of friction. After this the possibilities are considered which would result in a functional, practical arrangement of a carriageway surface (crossfall and texture) taking into consideration environmental constraints (road noise) and economic effects (tyre and road abrasion) for concrete surfacing and wet-carriageway conditions. To clarify the difficulties for the highway engineer in determining the optimal solution for the shape of the surfacing, the interdependence of the different parameters is shown in diagrams and tables. It appears particularly important from these that the significance of macro-roughness and drainage capacity grows in relation to increasing speed. In the case of concrete surfaces it is possible to form the required surface texture and the required roughness and skid resistance not only during the initial construction but also later when reinstating the skid resistant qualities.
