An analytical study of H15 bridges in Texas has resulted in an improved procedure for issuing overweight truck permits. Single and multiple axle limits, specifically to protest pavements rather than bridges, are assumed. The weight restrictions limit any (and all) axle groups as a function of the gage and tire contact widths. The restrictions were derived to assure that the maximum stress in any bridge member never exceeds the operating level. Only one vehicle is allowed on the bridge at a time but it is assumed to be traveling at a speed such that the full impact allowance is generated.

This synthesis will be of interest to pavement designers, highway administrators, and others concerned with pavement design, permit issuance and fees for overloaded trucks, and enforcement of truck weight laws. Information is presented on the effects that overloads have on pavements and on the methods of accommodating or controlling overloads. Highway pavements are designed for legal axle loads, and loads above these will significantly shorten pavement life. This report of the Transportation Research Board describes the effects on pavements of loads greater than those used in design, gives information on permit issuance and fees for overloaded vehicles, and describes the difficulties in enforcing truck weight laws.
