feature: CIRCUIT OF THE AMERICAS UP AND RUN Formula 1 racing has returned to the U.S.— and TXAPA members helped make it possible seat grandstand, the pit row and garages, a media building, an amphitheater with an observation tower, a conference center, medical buildings, pedestrian bridges and parking lots. But the project’s most important and detailed construction component was the track itself—the surface over which Formula 1 race cars will roar at speeds over 200 miles per hour. In January 2011, Austin Industries team member Tom Byrum gathered prospective bidders, the owners, and developers of the new F1 track together at TXAPA’s office in Buda, Tex., for a pre-bid meeting to discuss the layout and specifications of the facility and track. The European F1 team had never built a track in the United States and voiced concerns about some of Kyle Swaner F or the first time in five years, Formula 1 racing has returned to American soil. After months of negotiations and planning sessions with local officials and investors, Circuit of the Americas selected Austin to be the first permanent site of Formula 1 racing in the United States. The new track, located near State Highway 130 and FM 812, hosted its inaugural F1 race on November 16-18, 2012. the proposed production processes, specifically using continuous drum mix plants to produce hot mix asphalt instead of using batch plants. They needed reassurance that a continuous drum mix plant could be just as consistent as a batch plant. Technical Challenges Met The owners emphasized that there could be no cold longitudinal joints on the final riding surface of the track, which required echelon paving. The aerodynamics and low clearance of the race cars meant strict requirements for cross-slope and ride quality. The cross-slope had to be within +/- 3/8 inches (10 mm) for the asphalt base course, +/- 1/4 inches (7 mm) on the binder course and +/- 1/8 inches (3 mm) Construction Begins After getting the green light, TXAPA member company Austin Industries began putting together a highly qualified team to coordinate the massive $30 million project.
