National Asphalt Paving Association (NAPA)
The Sheldon G. Hayes Award winner is determined through a two-year process. Highway pavement projects using more than 50,000 tons of asphalt are eligible for consideration. Initially, they must win a Quality in Construction (QIC) Award, which is determined by numerical scores given by pavement engineers at the National Center for Asphalt Technology (NCAT) on the basis of how well the contractor met the specifications and achieved density on the finished pavement. All the pavements that meet a benchmark figure are given the QIC award.
The year after a project wins a QIC Award, it may be considered for the Sheldon G. Hayes Award. The top-ranked projects from each year are tested for smoothness, then visually inspected by an independent pavement consultant with many years of experience in the industry. This year, the evaluators praised the contestants for high-quality construction practices resulting in smooth, safe, and durable pavements.
2013 Finalist- Heartland Asphalt, Inc.
US HWY 14, Butler County, IA
Heartland Asphalt Inc. and the Iowa Department of Transportation were named a finalist for Heartland Asphalt’s work on State Route 14 in Butler County, Iowa. “It was an old concrete road with significant joint problems; riding on it was like driving a car with square wheels,” said George Jessen, president and general manager of Heartland Asphalt The work the company performed over a two-year period smoothed out the bumpy road, transforming it into an exceptional pavement.
To minimize inconvenience to motorists, the company kept one lane of the two-lane road open to traffic at all times during the paving operation.
During the first contract year, Heartland Asphalt performed full-depth patching on the existing concrete road, installed subdrains, and widened the pavement by 2–3 feet on each side to get a consistent 28-foot width for the road. The company then placed a 2-inch lift of asphalt over the old concrete.
In 2012, Heartland Asphalt returned to lay a second intermediate lift and a 1.5-inch surface course. The company also built 8-foot granular shoulders and installed grooved pavement markings. Additional work on the project included removal of an old railroad overpass along the route.
Heartland Asphalt used sustainable paving technology for the project, incorporating 20 percent reclaimed asphalt pavement (RAP) in the underlying layers and 15 percent RAP in the surface mix.
The company took much of the irregularity and bumpiness out of the road with first lift of asphalt. When the project was completed, Heartland Asphalt earned 90 percent of the possible incentive pay for the road’s smoothness.
“This was a pretty straightforward, well-run project and everything went well from the beginning to the end,” said Roy Gelhaus, Iowa DOT District 2 resident construction engineer. Cooperation and coordination between the state and the contractor helped make the job a success, he added. “The product that Heartland Asphalt put out was a very smooth pavement.”
