WIDE-BASE TRUCK TIRE EFFECTS ON PAVEMENT PERFORMANCE AND VEHICLE REGULATORY LEGISLATION
Current operating practice in the trucking industry related to tire pressures and truck tires are summarized. Findings of recent (since 1987) pertinent pavement performance research including both full-scale and analytical pavement response and performance studies are discussed. Pertinent findings developed in previous literature reviews are also included. Regulatory approaches developed by the various states based on information from a telephone survey conducted during July and August 1991 are included. Economic analyses are used to compare the increased annualized bituminous pavement rehabilitation costs with trucking industry benefits. Recommendations regarding the regulations of wide-base truck tires are presented. General conclusions can be drawn that: Wide-base truck tires appear to be between 30 percent and 100 percent more damaging to asphalt concrete pavement when rutting is the predicted or measured distress; and, Wide-base truck tires appear to be between 10 percent and 100 percent more damaging to asphalt concrete pavement when fatigue or alligator cracking in the wheel paths is the predicted or measured distress. Increased tire inflation pressures in all truck tires increase asphalt pavement damage. However, the potential for increased asphalt concrete pavement damage appears to be greater for wide-base tires with elevated inflation pressures than for conventional dual truck tires.
