Study Data Selection Criteria

  • Asphalt pavements
  • Federal aid eligible roads
  • 1st applied treatment ever or after a heavier treatment
  • 3 rating points before and after treatment
  • Only rating data prior to 2000

Points To Take Away

Study looked at worst case analysis for ESL Local agencies are collecting high quality data Local agencies gain significant benefit with treatments Cost effective analysis should drive practice You have the data and tools to do this yourself
