The maximum gross vehicle weight allowed on a “federal-weight-law truck” is 80,000 pounds, with four of its five axles carrying 17,000 pounds each and the steering axle carrying 12,000 pounds. The maximum allowable gross vehicle weight on the heaviest “Michigan-weight-law truck” is 164,000 pounds, which can only be achieved by use of eleven properly-spaced axles. Most of these axles carry only 13,000 pounds each. The alternative to a single Michigan combi-nation carrying 160,000 lbs. on 11 axles is two standard trucks carrying 160,000 lbs. on 10 axles. Pavement research has shown that these two smaller trucks actually cause about 60 per cent more pavement damage than does the single heavier truck, because of their higher axle loadings and the extra weight of an additional tractor at about ten tons.
