THE EFFECT OF ROAD SURFACING TEXTURE ON TIRE WEAR

TESTS CARRIED OUT TO ASSESS THE EFFECT OF ROAD SURFACE CHARACTERISTICS ON TIRE WEAR ARE DESCRIBED. THE WORK WAS PROMPTED BY THE CURRENT TREND TOWARDS HARSHER AND ROUGHER SURFACES FOR IMPROVING WET-ROAD SKIDDING RESISTANCE. TWO TECHNIQUES FOR WEARING TIRES IN A CONTROLLED MANNER WERE USED: A FIFTH-WHEEL METHOD IN WHICH THE WHEEL WAS FORCED TO RUN AT A FIXED SLIP ANGLE AND A METHOD IN WHICH A VEHICLE WAS MADE TO EXECUTE FIGURE-OF-EIGHT MANEUVERS THUS WEARING THE TEST TIRE WHICH WAS FITTED TO A FRONT WHEEL, THE TEST SURFACES WERE THOSE ON THE ROAD RESEARCH LABORATORY TRACK WHICH COVER A WIDE RANGE OF TEXTURE AND SKIDDING RESISTANCE. MEASUREMENT OF WEIGHT LOSS OF THE TIRE WAS USED TO ASSESS THE WEAR. INCREASE IN ROUGHNESS OF THE SURFACES WAS FOUND TO HAVE A RELATIVELY SMALL EFFECT ON WEAR, THE MAJOR FACTOR BEING SURFACE HARSHNESS. /RRL(A)/
