REVIEW OF LABORATORY AND FIELD METHODS OF MEASURING ROAD SURFACE FRICTION

THE CONFERENCE HELD ON METHODS OF MEASURING ROAD SURFACE FRICTION IS DISCUSSED IN ACCORDANCE WITH THE FOLLOWING MAJOR SECTIONS: (1) EXCHANGE OF AVAILABLE INFORMATION WITHIN EACH OF THE INDIVIDUAL FIELDS AND BETWEEN THESE FIELDS RELEVANT TO THE PROBLEM OF ADEQUATE TRACTION, (2) THE INVENTORY OF EXISTING KNOWLEDGE OF THE SUBJECT, (3) THE INVENTORY OF EXISTING DEFICIENCIES IN THE PRESENT KNOWLEDGE AND PRACTICES, (4) DEVELOPMENT OF A COMPREHENSIVE PROGRAM OF RESEARCH, AND (5) DEMONSTRATION AND CORRELATION OF TEST RESULTS OF EXISTING EQUIPMENT AND METHODS FOR MEASURING SKID RESISTANCE TO INITIATE A PROGRAM TO DEVELOP STANDARD TESTING PROCEDURES. IT IS RECOMMENDED THAT THE STANDARD METHOD SHOULD: (1) MEASURE THE SLIDING COEFFICIENT SINCE THAT CONDITION IS THE ONE MOST FREQUENTLY MET IN SKIDDING ACCIDENTS, (2) UTILIZE REALISTIC PASSENGER CARLOADS AND TIRE PRESSURES, (3) BE CAPABLE OF BEING RELIABLY USED OVER THE SPEED RANGE NORMALLY EMPOLYED BY PASSENGER VEHICLES, (4) BE CAPABLE OF RELIABLY MEASURING ANY PORTION OF A ROAD SURFACE, (5) BE USABLE IN ALL TYPES OF TRAFFIC WITHOUT HAZARD TO ANYONE, (6) PROVIDE A CONTINUOUS AND PERMANENT RECORD OF THE FORCE MEASUREMENTS AND THE SPEED OVER THE SITE BEING TESTED, (7) BE INDEPENDENT OF OPERATOR VARIABLE, (8) BE DESIGNED SO THAT WEIGHT SHIFT VERTICALLY WOULD NOT AFFECT RESULTS SIGNIFICANTLY, AND (9) UTILIZE A STANDARD TIRE THAT CAN BE MADE AVAILABLE OVER A LONG PERIOD OF TIME, AND HAS A STANDARD COMPOSITION, CARCASS AND TREAD DESIGN.
