Ten departments of transportation were named winners of the 2016 Perpetual Pavement Award by Asphalt Pavement Association (APA). The award celebrates long-life asphalt pavements that reflect the 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. 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 12 years. The road must demonstrate excellence in design, quality in construction, and value to taxpayers.
Engineers at the National Center for Asphalt Technology (NCAT) at Auburn University, evaluated the nominations and validated the results for this year's Perpetual Pavement Award winners. Since the Perpetual Pavement Award was first presented in 2001, 118 pavements in 30 U.S. states and one Canadian province have been honored with the award.
