WEAR OF PAVEMENT SURFACES CAUSED BY STUDDED TIRES /IN FRENCH/

THE EFFECT OF STUDDED TIRES ON PAVEMENT SURFACES HAS BEEN STUDIED BY MEANS OF A CIRCULAR TEST TRACK AT THE PONT-A- MOUSSON RESEARCH CENTRE. THE APPARATUS CONSISTS OF A CIRCULAR ASPHALTIC CONCRETE TRACK ON WHICH A SELF-PROPELLED CARRIAGE FITTED WITH A PAIR OF HEAVY VEHICLE WHEELS RUNS AT VARIABLE RADII OF GYRATION. THE LOAD PER WHEEL MAY VARY FROM 5 TO 10 TONS, AND THE SPEED RANGE IS 8 TO 60 KILOMETRES AN HOUR. IT HAS BEEN ESTABLISHED THAT: THE WEAR CAUSED BY STUDDED TIRES IS PROPORTIONAL TO THE NUMBER OF TIMES THEY PASS OVER THE PAVEMENT, WEAR INCREASES IN PROPORTION TO THE LOAD, AND THE AVERAGE DEPTH OF WEAR IS 4 MM FOR 10,000 PASSAGES AT 60 KM/HR FOR AN AXLE LOADED TO 13 TONS. UNDER THESE CONDITIONS, IF ALL VEHICLES WERE FITTED WITH STUDDED TIRES, A ROAD CARRYING 10,000 VEHICLES A DAY, 20% OF THEM HEAVY VEHICLES, WOULD UNDERGO WEAR CORRESPONDING TO 200 TONS OF BITUMINOUS MIX OVER A WINTER PERIOD OF 100 DAYS. SOME TRAFFIC SURVEYS HAVE SHOWN THAT IN EASTERN FRANCE 40% OF HEAVY VEHICLES ARE COMMONLY FITTED WITH STUDDED TIRES. THE SITUATION THEREFORE ALREADY GIVES CAUSE FOR CONCERN. /AUTHOR/
