EFFECTS OF CARBIDE STUDDED TIRES ON ROADWAY SURFACES

THE NATIONAL INTEREST AROUSED BY THE INTRODUCTION OF TUNGSTEN CARBIDE STUDDED TIRES TO AMERICAN AND CANADIAN MARKETS WAS SHARED BY THE MARYLAND STATE ROADS COMMISSION. PRELIMINARY TRIALS WITH LOCKED BRAKES SHOWED THAT THESE TIRES WOULD SCORE PAVEMENT SURFACES. THE COMMISSION THERE- FORE DIRECTED ITS BUREAU OF RESEARCH TO PREPARE A PROPOSAL FOR FIELD INVESTIGATIONS OF PAVEMENT SURFACES, AS AFFECTED BY THE USE OF THESE TIRES. THE PROPOSAL WAS SUBMITTED TO THE U.S. BUREAU OF PUBLIC ROADS AND ACCEPTED FOR INCLUSION IN THE FISCAL 1965 HPS-HPR PROGRAM. TWO TEST LOOPS WERE CHOSEN, ONE FOR TRUCKS, ONE FOR PASSENGER VEHICLES, EACH LOOP INCLUDING BOTH RIGID AND FLEXIBLE TYPE SURFACES. BOTH FRONT AND REAR TIRES OF ALL TEST VEHICLES WERE EQUIPPED WITH STUDDED TIRES. TEN THOUSAND CIRCUITS OF THE TEST VEHICLES WERE MADE AT EACH TEST LOOP. REFERENCE MARKERS WERE PLACED AT NUMEROUS LOCATIONS, AND THE AMOUNT OF PAVEMENT WEAR WAS DETERMINED BY DEPTH GAGE MEASUREMENTS. SIGNIFICANT WEAR OCCURRED AT BOTH TEST LOOPS. THE LIMITED TESTS DESCRIBED IN THIS REPORT SHOW THAT A CERTAIN AMOUNT OF DAMAGE WAS DONE TO THE HIGHWAY PAVEMENT SURFACES TESTED. IT IS CONSIDERED UNDESIRABLE TO GIVE UNLIMITED AUTHORITY FOR USE OF THESE TIRES UNTIL GENERAL OBSERVATIONS HAVE BEEN MADE OVER A PERIOD OF TIME. /AUTHOR/
