The Asphalt Pavement Alliance (APA) has announced the winners of its 2010 Perpetual Pavement Awards.

To be considered, pavements must be 35 years or older and never had a structural failure. The average interval between resurfacing must be no less than 12 years. Also, the road must demonstrate excellent design, quality construction, and provide value for the traveling public.

“Even though they've been punished by nearly 40 years of use, motorists are still using the original pavement structures,” says Mike O'Leary, APA co-chair. “The extraordinary performance of this pavement is worthy of attention.”

Engineers at the National Center for Asphalt Technology (NCAT) evaluated the nominations and a panel of industry experts validated the winners:

  • Alabama DOT: section of State Route 152 in Montgomery
  • Florida DOT: 4.3-mile section of northbound Florida State Road 45/U.S. Highway 41 in Sarasota County
  • Maryland State Highway Administration: section of MD 10 from MD 648 to I-695 in Anne Arundel County
  • Minnesota DOT: 5-mile section of U.S. Trunk Highway 61 from mile-posts 57.5 to 62.5
  • Rhode Island DOT: northbound lanes of a section of State Highway Route 114 — Wampanoag Trail between Mink Street and Massasoit Avenue
  • Tennessee DOT: 3.5-mile section of Hardeman County State Route 100
  • Each winner receives an engraved crystal obelisk and a plaque, and their names and the names of their projects are added to a permanent plaque that's kept at NCAT.
