  • Provides smooth and durable road surface with high friction coefficient
  • Material is widely available and cost-effective
  • Impervious quality channels water to the curb on crowned roadways
  • Dark color hides dirt and stains and creates background for high-contrast markings
  • Easy to maintain and patch
  • Can be pigmented or imprinted for varied purposes
  • Asphalt can be recycled


  • Prone to rutting and shoving under high volumes of heavy vehicles
  • Contributes to heat-island effect
  • Sends runoff to catch basins, thereby contributing to combined-sewer overflows (CSOs) during large rainstorms


  • Standard for roadbeds of all city streets unless otherwise specified
  • Preferred road surface for cycling
  • DOT generally maintains this material
