AN OVERVIEW OF EUROPEAN MEASURING METHODS AND TECHNIQUES

The investigation of tire-road friction and its improvement particularly on wet roads requires testing methods and equipment designed to record individually the characteristics of the road on the one hand and of the tire on the other. Additional methods are needed to measure and evaluate the interaction of the tree partners: road, tire, and motor vehicle. Aim and purpose of the planned investigation determine the choice of measuring equipment and methods. Road construction concerns need characteristic values for evaluating the skid resistance of road surfaces when new and its changes through use, brought about by traffic, wear and weather. The automobile industry is more interested in the effect of tire-road friction on the directional control properties of the vehicle and therefore prefers road tests with vehicles where car handling can be examined. Tests conducted by tire engineers seek to establish the extent of tire-road friction as well as the interaction of tire and vehicle on a given road surface. A number of basic investigations are conducted on drum test machines. As a result, different measuring methods are used in road construction, and in the automobile and tire industries, because of the different purposes that the measurements are to serve. The paper will describe the principles fundamental to the measuring methods and techniques used in Europe, discussing their possibilities and limitations, and pointing cut the requirements that have proved indispensable to ensure the reproducibility and comparability of the results of the measurements. /Author/
