  • Provides durable road surface with high friction coefficient
  • This material is widely available and cost-effective
  • Resists rutting and shoving that can occur with asphalt
  • Compared to asphalt, reduces impact of vehicle travel vibrations on sub-surface features and neighboring structures
  • Higher SRI than asphalt, which helps reduce urban heat island effect


  • Difficult and more expensive to replace or patch in sections where utility cuts or defects occur
  • Noisier than asphalt


  • May be considered for use in Shared Streets
  • Appropriate for roads with high motor vehicle volumes and/ or gross weight
  • Should be used wherever engineering criteria dictates, such as bridges, vaulted roadways, or bus pads
  • Should not be used where frequent utility cuts are likely
  • Will be evaluated case-by-case based on engineer review of roadway structure
  • DOT generally maintains this material
