THE EXPLOITATION OF HIGHWAYS -- CHAPTER 7: INFLUENCE OF ROAD SURFACING CONDITIONS ON VEHICULAR TRAFFIC -- EVALUATION OF THESE CONDITIONS /IN RUSSIAN/
THE SURFACE CHARACTERISTICS OF ROADS CAN BE EVALUATED BY A LARGE NUMBER OF CRITERIA: SIMPLE CRITERIA SUCH AS PROFILE EVENESS, SLIPPERINESS, AVERAGE SPEED, AND COMPLEX CRITERIA LIKE DAMAGE AND TRAFFICABILITY. THE VARIOUS TYPES OF EQUIPMENT DEVELOPED FOR EVALUATING THESE CRITERIA ARE DESCRIBED. AN IMPORTANT ASPECT OF THE EVALUATION IS THE SPEED AT WHICH MEASUREMENT RESULTS ARE ANALYSED. NORMALLY TWO CRITERIA ARE USED TO DECIDE WHETHER A SECTION OF ROAD NEEDS TO BE IMPROVED: ADHESION MEASURED BY MEANS OF A TRAILER WHICH GIVES THE COEFFICIENT OF LONGITUDINAL FRICTION WITH A BLOCKED WHEEL AND A TRAFFICABILITY INDEX. /TRRL/
