The Texas legislature has authorized the issuance of annual permits allowing commercial motor vehicle operators to operate nonagricultural vehicles exceeding the legislative mandated axle weight by 10 percent and the allowable gross vehicle weight by 5 percent, with heavier loads allowed for agriculture. The $75 permit (and $15,000 bond) allows operation on state and county roads except the interstate system. The interpretation has been that this effectively allows 84,000 lb vehicles on roads designed for 58,420 lb vehicles. The study included a full scale truck loading experiment on two County roads and one State highway. General agreement with AASHTO damage models was found. Surveys of state and county agencies as well as the trucking industry were conducted. In general, the trucking industry showed substantial cost savings with the increase in load. Government agencies responsible for pavement and bridge management did not obtain receipts from the permit fee sufficient to offset maintenance and enforcement costs associated with this management activity.
