—Awarded the "Pavement Smoothness Award" for exceptional efforts in providing quality construction, which led to the smoothest Multi-Lift Asphalt Overlay project constructed on the National Highway System in the State of Louisiana in 2002 on Interstate 12 and 2003 on Interstate 10.

—The Quality in Construction Award recognizes Hot Mix Asphalt (HMA) pavements of excellence. "NAPA selects the recipients of its paving awards using a known set of standards that have been shown to give a good result," commented David B. Carlson, Chairman of the NAPA Board of Directors. "This award demonstrates the high quality of work that the HMA industry is achieving."

—Diamond B Construction Co., LLC won a Quality in Construction Award for its work on Interstate 10 in Jefferson Davis Parish. Because the road's average daily trips numbered more than 42,000, the company faced restricted paving during rush hours. It met the challenge by doing some nighttime paving and by emphasizing safety for its workers and motorists. The use of informal partnering with the state helped the contractor complete the project 119 days ahead of schedule, while producing a smooth, high-quality pavement. Pavement ride quality was 72% below the minimum acceptable smoothness requirements.

—The second NAPA award-winning project was the rubblizing and overlay of Interstate 12 in Livingston Parish. Challenges included the high volume of paving to be done, nighttime paving, and innovative paving techniques to help keep the mat smooth. The company successfully partnered with the state on this project, completing it 23 days ahead of schedule. Pavement ride quality was 66% below the minimum acceptable smoothness requirements.
