Abstract:

Texas has approximately 17,500 miles of load-zoned pavements, comprising over 20 percent of the number of centerline miles on the state-maintained system. These pavements are primarily low-volume farm-to- market roads constructed in the 1950s at a time when legal load limits were lower than they are now. About 98 percent of the load-zoned pavements in Texas are posted with a gross vehicle weight (GVW) restriction of 58,420 lbs. While load limits based on gross vehicle weight are simple to implement, the procedure is fundamentally flawed since the gross load from a vehicle is transmitted through the axle tires. Recognizing the need for a better methodology of determining load limits, the Texas Department of Transportation (TxDOT) sponsored a project with the Texas Transportation Institute (TTI) to develop a procedure for evaluating load restrictions on the basis of axle load and axle configuration.
