Eight departments of transportation have won the 2017 Perpetual Pavement Award by Asphalt Pavement Alliance (APA).
They were honored for long-life asphalt pavements that reflect characteristics of a Perpetual Pavement design.
The award is presented to state transportation departments and local agency road owners for well-performing asphalt pavements that are at least 35 years old with proven high-quality structural design, according to a press release from the group.
The 2017 winners:
- Alabama Department of Transportation, North Region, for a 4-mile section of four-lane divided highway on U.S. Highway 72/State Route 2 in Jackson County, from County Road 11 to SR 79. This is the ninth Perpetual Pavement Award for ALDOT.
- Arkansas Department of Transportation for a 2-mile stretch of two-lane Arkansas Highway 24/Section 6 in Ouachita County. This is the eighth Perpetual Pavement Award for ARDOT.
- Florida Department of Transportation for a 4.265-mile section of rural two-lane arterial roadway on Florida State Road 50 in Sumter County. This is the eighth Perpetual Pavement Award for FDOT.
- Minnesota Department of Transportation for a 4.75 section of two-lane road on Minnesota State Highway 89 in Beltrami County. Sixteen MnDOT pavements have earned a Perpetual Pavement Award, more than any other state.
- Pennsylvania Department of Transportation, Engineering District 3-0, for a 4.5 section of two-lane road on State Route 3010 in Columbia County. PennDOT has earned seven Perpetual Pavement Awards.
- South Carolina Department of Transportation for a 9-mile section of four-lane divided highway on Interstate 95 in Jasper County. SCDOT has earned seven Perpetual Pavement Awards.
- Tennessee Department of Transportation for a 3.7-mile stretch of two-lane highway on State Route 88 in Lauderdale County. This is the 13th Perpetual Pavement Award earned by TDOT.
- Washington State Department of Transportation for a 4.42-mile section of four-lane divided highway on State Route 16 in Pierce and Kitsap counties. This is the fourth Perpetual Pavement Award earned by WSDOT.
To earn the award, the pavement must have not suffered a structural failure, and it should have an average interval between resurfacings of no less than 13 years. The pavement is judged on excellence in design, quality construction and value for taxpayers, officials say.
“One of the keys to sustainability is long life,” said Amy Miller, P.E., national director of the Asphalt Pavement Alliance.
“These Perpetual Pavement Award-winning roads demonstrate how asphalt roads can be engineered to last indefinitely with only routine maintenance and periodic surface renewal.”
NCAT evaluates entrants and chooses the winners
Engineers at the National Center for Asphalt Technology (NCAT) at Auburn University selected the eight 2017 Perpetual Pavement Award winners.
Winning agencies are honored by their local state asphalt pavement association and are presented with an engraved crystal obelisk.
The names of the winning agencies and projects are added to a plaque on permanent display at the NCAT Research Center at Auburn University.
Since the Perpetual Pavement Award was first presented in 2001, 126 pavements in 30 U.S. states and one Canadian province have been honored with the award.
The concept of Perpetual Pavements
The concept of Perpetual Pavements was introduced in 2000 by the Asphalt Pavement Alliance.
It’s a partnership of the Asphalt Institute (AI), National Asphalt Pavement Association (NAPA) and the State Asphalt Pavement Associations.
Perpetual Pavement is defined as “an asphalt pavement designed and built to last longer than 50 years without requiring major structural rehabilitation or reconstruction, and needing only periodic surface renewal in response to distresses confined to the top of the pavement”
