  • A1: 12.8 feet x 246 feet
  • A7: 9.4 feet x 246 feet
  • A8: 16 feet x 328 feet
  • A9: 16 feet x 492 feet

  • A1: Concrete / Smooth / Smooth / N/A
  • A7: Asphalt / Rough / Smooth / Limestone
  • A8: Sand Asphalt / Smooth / Smooth / Granite
  • A9: Asphalt / Rough / Smooth / Limestone

Usage / Features

  • Wet braking and wet traction testing
  • Standard water depth for adherence plateau is 1.2mm
  • A1: IRI = 38.9 in/mile
  • A8: IRI = 68.1 in/mile
  • A9: IRI = 66.3 in/mile
