Presentation Transcript

  1. Pavement Cost Analysis for Special or Permitted Vehicles A New Spreadsheet Program Based on MEPDG Results, WIM Data, and Highway System Data

  2. Overview of Pavement Cost Model • Model estimates pavement costs for specific vehicles and types of trips • Model can use national average data, state default data, or user-supplied data • After state customization, as needed, model is simple to use • User supplies vehicle axle weights and trip information

  3. User Inputs • Axle weight for each axle group (tandems and tridems are each considered one axle group) • Number of axles in each group • Miles of travel on Interstate, State, and Local roads

  4. Results • Cents per mile of travel • Total costs in dollars • Costs shown by highway system as well as for total trip

  5. 71 Kip Five-Axle Single-Trailer (3S2)

  6. 80 Kip Five-Axle Single-Trailer (3S2)

  7. 97 Kip Six-Axle Single-Trailer (3S3)

  8. Underlying Data • Axle load equivalency factors (LEFs) based on thousands of runs of MEPDG pavement model • Costs per mile based on national current pavement expenditures per truck mile • Load-related share of pavement costs based on recent state cost-allocation studies • Baseline axle loads based on 190 million truck weight observations in 46 states

  9. Options to Customize • States can use their pavement knowledge to modify pavement distress distributions • States can enter their own detailed pavement cost information • States can update WIM data • States can combine and weight the default data from adjacent states
