The Asphalt Pavement Alliance (APA) recently honored the Michigan Department of Transportation (MDOT) with its Perpetual Pavement Award for a 5.2-mile section of M-24 that runs from the north village limits of Mayville, MI to M-46. The project was one of 11 projects across the United States that was honored for 2007.
The award is given to owners of asphalt pavements that are at least 35 years old and have never had a structural failure. The average interval between resurfacing of each awarded pavement must be no less than 13 years. The road must demonstrate the qualities expected from long-life asphalt pavements: excellence in design, quality in construction and value to the traveling public.
Engineers at the National Center for Asphalt Technology (NCAT) evaluated the nominations for the Perpetual Pavement Award and a panel of industry experts validated the recipients.
“Even though each of these pavements has been punished by more than 35 years of heavy use, motorists are still using the original pavement structures. The only maintenance that has been done has been periodic replacement of the surface,” said Mike O’Leary, APA co-chairman. “The extraordinary performance of these pavements is worthy of attention.”
“Perpetual pavement is an industry standard that is extremely well represented by these award recipients,” added Gaylen Ghylin, APA co-chairman. “Long life, durability and exceptional performance are hallmarks of hot mix asphalt. These pavements are testimonials to high-performance asphalt as a marriage of excellent design and quality construction.”
Each recipient receives an engraved crystal obelisk and a plaque, and has its name added to a permanent plaque that is kept at the NCAT Research Center. Presentations were made on November 12 at a special ceremony during the International Conference on Warm Mix Asphalt in Nashville, TN.
