RECOMMENDATIONS FOR AN INTERNATIONAL MINIMUM SKID RESISTANCE STANDARD FOR PAVEMENTS

THE NEED FOR MINIMUM INTERNATIONAL SKID-RESISTANCE REQUIREMENTS ON ROADS AND HIGHWAYS IS APPARENT FROM ACCIDENT STATISTICS IN SEVERAL COUNTRIES. THE INTERPRETATION AND IMPLEMENTATION OF ANY SUCH STANDARDS, HOWEVER, ARE MADE DIFFICULT BY THE MANY VARIABLES PRESENT WITH EXISTING TEST PROCEDURES. THESE INCLUDE TEST TIRE PARAMETERS, ENVIRONMENTAL FACTORS, AND PARTICULARLY THE MODE OF TESTING (LOCKING-WHEEL, STOPPING-DISTANCE, DECELERATION-SENSING, BRAKE AND SIDE-SLIP). IT IS RECOMMENDED THAT A MEANINGFUL INTERNATIONAL MINIMUM STANDARD SHOULD SPECIFY MINIMUM COEFFICIENTS OF FRICTION IRRESPECTIVE OF TEST METHOD AND AT TWO DISTINCT SPEEDS, PERHAPS 50 AND 90 KM/HR. PREVIOUS WORK HAS SUGGESTED THAT THE COEFFICIENT BE SPECIFIED AT TWO DISTINCT SPEEDS, SINCE PAVEMENTS WHICH PERFORM SIMILARLY AT ONE TEST SPEED MAY HAVE TOTALLY DIVERGENT COEFFICIENTS AT OTHER SPEEDS. SPECIFYING THAT THESE MINIMA ARE IRRESPECTIVE OF TEST METHOD IS AN ESSENTIAL CRITERION FOR ELIMINATING VARIATIONS, AND IS, OF COURSE, A MORE PRACTICAL APPROACH SINCE A SKID MAY OCCUR UNDER ANY CONDITION OF BRAKING OR CORNERING. IT IS BELIEVED THAT THIS OBJECTIVE CAN BE MET WITH THE USE OF CORRELATION PLOTS BETWEEN DIFFERENT TEST MODES, SUCH AS THOSE ALREADY ESTABLISHED IN SWEDEN AND THE NETHERLANDS. FUTURE TEST PROGRAMS CAN SERVE TO ESTABLISH A COMPREHENSIVE LISTING OF CORRELATION FACTORS FOR THE SUCCESSFUL IMPLEMENTATION OF ANY INTERNATIONAL STANDARD. /AUTHOR/
