Des Moines Asphalt and Paving has won a 2013 National Asphalt Pavement Association (NAPA) Quality in Construction Award – Green Pavement – in the over 50,000 tons category for excellence in construction of its asphalt pavement of Interstate 35 in Polk County, Iowa. The project, which covered 4.17 miles of interstate, was completed entirely at night during non-peak traffic times. 68,271 tons of hot mix asphalt which incorporated use of RAS was placed during work which lasted 54 nights. The average daily traffic count for this section of roadway is rated at 99,900 vehicles per day. The project consisted of four inches of ACC resurfacing utilizing 100M ESAL mix designs. The surface mix contained quartzite for L-2 skid resistance (both surface and intermediate) incorporated PG70-28 binder.

The work included a total of eight ramps on the northbound lanes and ten on the southbound lanes. Two high-speed ramps were required to remain open while work was performed in stages. The asphalt mix for the road’s base and paved shoulders contained 20 percent reclaimed asphalt pavement while the surface and intermediate courses contained four percent recycled asphalt shingles.

The project was completed at night and involved lane closures and a number of safety precautions for work crews and the traveling public. All workers wore highly reflective safety vests and shin leggings; some workers also chose to wear highly reflective hard hats equipped with flashing lights.

Des Moines Asphalt received its award of February 5th at a ceremony during the association’s 59th Annual Meeting in Boca Raton, Florida.
