Attendees of the NAPA Young Leaders Conference stand at the top of the hill at turn one on the Circuit of The Americas Formula 1 racetrack in Austin, Texas. Young Leaders See Future in Austin From High-Tech Paving Techniques to Leadership Lessons, the NAPA Young Leaders Conference Brings Value By T. Carter Ross F or the asphalt industry, the future gathered in Austin. The NAPA Young Leaders annual conference and tour gave the next generation of industry leaders opportunities to learn about innovations in paving and leadership strategies. Tying it all together was a tour of the Circuit of The Americas, the first purpose-built Formula 1 racetrack in the United States. The tour gave a look at the track barely two weeks before its first race, and while the track itself was complete, much of the surrounding facility was still an active construction zone. Founded in 1985, the NAPA Young Leaders program works to develop the next generation of industry leaders, helping them build connections and cultivate the skills and knowledge needed for innovation and growth at their companies. The Young Leaders includes both producer and associate members of NAPA, representing a wide cross section of the industry. “An industry like ours has been around for so long, but it’s changing rapidly,” said NAPA Young Leaders Chairman Patrick Nelson at the opening of the conference. “In my 20 years in the industry, I constantly see technologies and methods change so quickly.” Nelson noted that he’s been able to draw upon the experiences of fellow Young Leaders colleagues who, because they are from far-flung areas of the country, do not compete with his company, Lehman-Roberts Co. Technology Focus The educational portion of the meeting began with a discussion of high-density screed technology from Brodie Hutchins, Vice President of Distribution Development at Wirtgen America. He started off by noting the differences in how paving is accomplished in the United States versus Europe. In general, he said, paving in the States is handled at faster speeds, in thinner lifts, and with narrower widths. Naturally, these differences have led to differences in paving-machine technology, too, particularly in terms of the screeds. Hutchins said that with the sort of high- density screed systems used in Europe and elsewhere, thicker lifts can be placed without worry, resulting in less fuel usage during paving and greater density before compaction. In the U.S., interest in this technology has appeared particularly with base work, where a company may need to place a 10- to 12-inch layer, or with special mixes and projects, such as the Circuit of The Americas F1 track in Austin. Richard Mills, Vice President of Operations at Austin Bridge & Road, continued the educational program with a look at the Circuit of The Americas. His company was responsible for paving the 3.4-mile track and other portions of the 900-acre site. The Fédération Internationale de l’Automobile, the governing body for Formula 1 racing, had very exacting specs for the track. Meeting them required careful collaboration among the many stakeholders on the project to ensure its success. The 52-page paving plan specified that three pavers be used (four in some wider areas) continuously, stopping only at specified points, to ensure smoothness. Transverse joints could be only at specific locations exiting a curve. Exacting specifications were set for smoothness and compaction, too. “There is an important leadership lesson there,” said Mills. “It took a long time to build trust and lots of learning activities to ensure the trust and ability of everyone to work together.” As part of planning for the project, the Austin Bridge & Road team visited Russia to see an F1 paving project in Moscow, as well as Germany to meet with the equipment makers and the quality control consultants. Track Lessons In all, some 380,000 tons of total site work was competed at the track using three material transfer vehicles, four pavers, 10 rollers, and 40 trucks. On some of the paving days, the temperature soared to over 100°F, adding to the logistical challenges for the 18-hour paving days. continued on page 51 Asphalt Pavement Magazine – March/April 2013 • 49
