WSDOT Earns 5th Consecutive (7th overall) Perpetual Pavement Award for SR 395

Asphalt Pavement Alliance Announces Winners of 2020 Perpetual Pavement Award (PPA)

The Washington State Dept. of Transportation was notified on May 27th, 2021 that it has won a 2020 PPA from the Asphalt Pavement Alliance (APA). The award celebrates long-life asphalt pavements from across the USA that highlight the characteristics of a Perpetual Pavement design.  2020 PPA WA Press Release FINAL

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. To earn the award, the pavement must have not suffered a structural failure, and it should have an average interval between resurfacing of no less than 13 years. The pavement must demonstrate the characteristics expected from a long-life, Perpetual Pavement design: excellence in design, quality in construction, and value for the taxpayers.

The 2020 award winner in Washington state is for a 6.9 mile section of highway on State Route 395 in Franklin county. This is the seventh Perpetual Pavement Award earned by WSDOT.

“One of the keys to infrastructure sustainability is long pavement 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.”

Engineers at the National Center for Asphalt Technology (NCAT) at Auburn University, evaluated the nominations and validated the results for the 2018 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, 150 pavements in 35 U.S. states and one Canadian province have been honored with the award.
