SKIDDING AND SKID RESISTANCE

THE GENERAL PROBLEM OF VEHICLE SKIDDING IS OUTLINED, FOLLOWED BY A DISCUSSION ON THE NATURE OF ROAD FRICTION AND THE PRINCIPLES OF FRICTION MEASUREMENTS. VARIOUS PRACTICAL METHODS OF MEASURING PAVEMENT FRICTION, SUCH AS THE SIDEWAY FORCE METHOD, TRAILER DEVICES, STOPPING DISTANCE METHOD, DECELEROMETER TECHNIQUE, PORTABLE INSTRUMENTS, AND LABORATORY METHODS ARE COVERED. CERTAIN ASPECTS OF INTERPRETING SKID RESISTANCE MEASUREMENTS ARE SUMMARIZED: HOW RESULTS OBTAINED WITH DIFFERENT DEVICES COMPARE, WHAT ARE THE SKID RESISTANCE REQUIREMENTS FOR MODERN TRAFFIC, WHAT ARE THE GENERALLY ACCEPTED PRACTICAL STANDARDS, AND HOW CAN MEASUREMENTS BE SUPPORTED BY SKIDDING ACCIDENT STATISTICS. ROAD SURFACE PROPERTIES INFLUENCING SKID RESISTANCE ARE DISCUSSED, INCLUDING PAVEMENT TYPE AND FINISH, MIX COMPONENTS, SURFACE TEXTURE AND POSSIBLE COVERING, GEOMETRIC DESIGN, TOGETHER WITH THE VARIATION OF SURFACE PROPERTIES DUE TO WEATHERING, TRAFFIC WEAR, AND SEASONAL FACTORS. INFLUENCING FACTORS ASSOCIATED WITH THE VEHICLE ARE COVERED, SUCH AS THE PROPERTIES OF THE TIRE RUBBER, TREAD PATTERN, BRAKING SYSTEM, WEIGHT AND SPEED OF THE VEHICLE, ETC. FINALLY, THE PRESENTLY AVAILABLE PRACTICAL MEANS OF PREVENTING SKIDDING ACCIDENTS ARE POINTED OUT, SUCH AS DRIVING SKILLS, MECHANICAL DEVICES, AND ANTI-SKID ROAD CONSTRUCTION AND MAINTENANCE. /AUTHOR/
