• 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.
