Minnesota is Honored for its 14th Perpetual Pavement Award

Asphalt Pavement Alliance

Eight Departments of Transportation Honored for Success of Long-Life Asphalt Roads

Lanham, Md. — The Asphalt Pavement Alliance (APA) has recognized eight state departments of transportation with the 2015 Perpetual Pavement Award for high quality, long-life asphalt pavements.

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 road must demonstrate the characteristics expected from a long-life, Perpetual Pavement design: excellence in design, quality in construction, and value to taxpayers.

Minnesota Department of Transportation received the award for a 3.24-mile, two-lane section of SR 71 in Beltrami County from milepost 317.28 to 320.52. MnDOT has had 14 pavements recognized with the Perpetual Pavement Award, more than any other state or agency.

Steady Increase in Sustainability of Asphalt Pavements

Recycled Materials, Warm-Mix Asphalt Show Steady Growth Increasing the Sustainability Profile of Asphalt Pavements

Lanham, Md. — Nationwide, asphalt pavement mix producers continue to improve the sustainability profile of America’s roads through the incorporation of recycled materials and the use of energy-saving warm-mix asphalt technologies.

According to the latest survey of asphalt mix producers conducted by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), more than 75 million tons of recycled materials — primarily asphalt pavement material reclaimed from old roads and parking lots and recycled asphalt roofing shingles — was put to use in new asphalt pavement mixtures during the 2014 construction season.
