2011 Ray Brown Airport Pavement Award
The Ray Brown Airport Pavement Award is given to the highest-rated Quality in Construction - Airport Pavement . The award is named after Ray Brown, who was the Director of the National Center for Asphalt Technology from 1991 until his retirement in 2007. Under his leadership, NCAT became the preeminent organization for asphalt pavement research.
The award was given for the first time at the 2012 Annual Meeting.

The outstanding project was the rehabilitation of Runway 5-23 at Craig Municipal Airport in Jacksonville. “The runway had last been resurfaced about 15 years ago, and there were quite a few cracks that were forming at the center line and starting to spider out from the shoulder,” said Chris Wright, the company’s project manager. “The airport authority had many complaints from the pilots about the condition of the runway.”
The runway originally measured 3,650 feet long and 100 feet wide with 25 feet of shoulder. At the request of the airport, Duval Asphalt Products narrowed the shoulders down to 12 feet and converted the remaining area to grass. It also built a 150-foot by 120-foot blast pad to extend the runway at its west end.
Company crews profile-milled the entire runway to obtain the required elevations, then performed about 80,000 linear feet of crack filling. They then placed a leveling course in several lifts to meet the elevation of the blast pad extension.
To help ensure smoother pavement joints, Duval installed a pavement fabric in 18-inch minimum strips on the entire centerline joint and on the adjacent existing joints located 12 feet on either side of the centerline. Workers then laid a 0.5-half inch leveling course of 1,800 tons of Superpave mix over the entire runway, followed by a 5,000-ton, 1.5-inch Superpave surface course. The company employed a leveling ski to attain the right pavement depth and a material transfer device during paving to prevent segregation problems and enable continuous paving.
The runway was closed during paving and most work was done during the day, except for the tie-in to Runway 14-27, which crews completed at night.
The result was a very smooth and consistent runway surface. “It ended up being a really good job. The people who work at the airport and the aviation authority are all very happy,” said Wright.
