• Abstract:
  The largest loads on public road systems disproportionately inflict the greatest damage to highway
  
  infrastructure. Simultaneously facing both increasing demand for overweight loads and deteriorating
  
  pavement and bridges, the South Carolina Department of Transportation commissioned this study to
  
  investigate the impact of heavy vehicle traffic on pavements and bridges in South Carolina and to
  
  develop policy recommendations based on technical analysis and the modern institutional environment
  
  in South Carolina. To conduct this study, Clemson University estimated pavement and bridge
  
  deterioration, investigated the adequacy of standard practices in state agencies for dealing with this
  
  deterioration, and characterized how stakeholders in South Carolina’s trucking industry perceive those
  
  practices.
  
  The pavement models revealed that overweight trucks reduce pavement service life significantly
  
  beyond design standards. Results from the bridge model indicated that bridge damage increased
  
  exponentially with an increase in truck weight. Recovering damage for South Carolina’s highways will
  
  require a flat fee of $65 per trip, but traditional flat fees for overweight loads fail to charge fairly
  
  according to the differing level of damage from distributions of vehicle weights, axle configurations,
  
  and trip length. Several alternative fee structures are presented, such as an axle-based system in
  
  which permits will cost between $24 and $175 per trip according to load, vehicle configuration, and trip
  
  distance.
  
  Stakeholder interviews indicated differing opinions on the objectives of user fees for permitting
  
  overweight loads; however, many stakeholders indicated a need to address illegal loads and establish
  
  consistent fee structures across the Southeastern mega-region. SCDOT and trucking industry
  
  representatives should work together in an ongoing focus group to develop common understanding of
  
  issues, consensus around objectives, and provisions for fairness that will address industry concerns.
