Pavement Cost Analysis for Special or Permitted Vehicles

A New Spreadsheet Program Based on MEPDG Results, WIM Data, and Highway System Data

overview of pavement cost model
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
user inputs
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
results
Results
  • Cents per mile of travel
  • Total costs in dollars
  • Costs shown by highway system as well as for total trip
underlying data
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
options to customize
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
