Load Rating Choice and Longer Combination Vehicle Impacts on the Rural Interstate Bridge Network
Year: 1991
Type: article
Abstract: The paper describes the results of a survey of U.S. State Highway Departments in which 60% of the 47 responding states recommended using the Inventory Bridge Rating for the operation of longer-combination vehicles. Calculations for double 48 ft and triple 28 ft vehicle configurations show that the choice of bridge rating criterion dramatically affects predicted longer-combination vehicle impacts on the rural Interstate network. Employing these vehicle types and the Inventory rather than Operating Rating on the rural Interstate network produces 309% more deficient bridges, 531% higher affected traffic volumes, and 335% higher replacement costs. The replacement cost rating differential exceeds $6 billion, excluding user delay costs.
