Twelve departments of transportation (DOTs) in the U.S. were named winners of the 2020 Perpetual Pavement Award (PPA) by the Asphalt Pavement Alliance (APA).
This number ties last year’s record of awards in a single year since the awards were first presented in 2001. The award celebrates long-life asphalt pavements that reflect the characteristics of a perpetual pavement design.
The award is presented to state DOTs 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.
Engineers at the National Center for Asphalt Technology (NCAT) at Auburn University evaluated the nominations and validated the results for the 12 winners for 2020. Since the PPA was first presented in 2001, 156 pavements in 31 U.S. states and one Canadian province have been honored with the award.

“One key indicator of quality in construction is a smooth, long-life pavement,” said Amy Miller, P.E., National Director of the APA. “Long-life asphalt pavements serve the community, reduce the money needed for maintenance and conserve raw materials, ultimately leading to a truly sustainable structure that exemplifies the triple bottom line.”
