Test Tracks & Facilities

Road B - Low & Middle

  • Opened in 2007
  • Consists of two separate tile testing surfaces - each with different coefficients of friction
  • Water is applied via underground sprinkler system capable of
    watering both tile surfaces individually as well as the asphalt in between the first 350 feet of tile, at the same time or separately.
  • Low friction ceramic tiles (simulating ice)
    • Designed friction coefficient of 0.09 – 0.12 (wet)
    • 700 feet in length
    • 30 ft wide (at widest point)
  • Middle friction basalt tiles (simulating snow)
    • Designed friction coefficient of 0.25 – 0.35 (wet)
    • 700 feet in length
    • 51 feet wide (at widest point)
  • Approach to the tile surfaces
    • 1,350 ft in length
    • Straight, level, asphalt road
    • Designed friction coefficient of 0.95 +/- 0.05 (dry)
  • Possible configurations include:
    • High μ only
    • Low μ only
    • Low μ/ High μ split (both directions)
    • Low μ/ Wet asphalt split (both directions)
    • Mid μ only
    • Mid μ/ High μ split (both directions)
    • Mid μ/ Wet asphalt split (both directions)
    • High μ/ Low μtransition
    • Low μ/ High μ transition
    • High μ/ Mid μ transition
    • Mid μ/ High μ transition
