DETERMINATION OF THE WEAR CAUSED TO ROAD PAVEMENTS BY VARIOUS TYPES OF TYRES

STUDDED TYRES HAVE SINCE THEIR INTRODUCTION IN THE EARLY SIXTIES UNDERGONE DEVELOPMENTS WHICH IMPROVED THEIR ROADHOLDING CHARACTERISTICS WHILE AT THE SAME TIME REDUCING THEIR AGGRESSIVENESS WHERE PAVEMENTS NOT COVERED WITH SNOW OR ICE ARE CONCERNED. THE PRESENT WORK, CARRIED OUT ON THE PAVEMENT WEAR TEST RIG OF THE ESSO AG IN HAMBURG, HAD THE OBJECT OF DETERMINING THE PAVEMENT WEAR CAUSED BY THE NEW STUDDED TYRES AND ALTERNATIVE WINTER TYRES WITHOUT STUDS AS COMPARED WITH THE CURRENT STUDDED TYRES AND NORMAL SUMMER TYRES. THE TEST RIG PRODUCES COMBINED SLIP AND OSCILLATORY MOVEMENT OF THE CAR WHEEL. WHILE THE WHEEL IS GIVEN VERTICAL OSCILLATIONS BY MEANS OF HYDRAULIC ACTUATORS, THE ROAD SURFACE (TEST PIECE) MOVES TO AND FRO UNDER THE TYRE WITH A UNIFORM VELOCITY OF 1,2 M/MIN. THE ABRASION OF THE ROAD SURFACE IS ESTIMATED BY MEASURING THE LOSS OF HEIGHT OF THE SAMPLE AND ALSO BY CALCULATION FROM THE AMOUNT OF ABRADED MATERIAL. TESTS WERE CONDUCTED USING ELEVEN TYPES OF TYRES AND THREE KINDS OF ROAD SURFACING (ASPHALT CONCRETE 0/11 MM, POURED ASPHALT 0/11 MM, AND ASPHALT MORTAR 0/8 MM). A CALCULATED COMPARATIVE AGGRESSIVENESS SHOWED THAT THE IMPROVED TYPES OF STUDDED TYRES REDUCED PAVEMENT ABRASION COMPARED WITH THE OLDER TYPES OF TYRE BY SOME 60% BY VIRTUE OF THE REDUCTION IN THE NUMBER AND PROJECTION OF THE STUDS AND ALTERATIONS OF THE FLANGES AND BEDDING IN THE TYRE. TYRES WITHOUT STUDS DID NOT CAUSE ANY PERCEPTIBLE ABRASION AT ALL.
