Circuit of The Americas has begun an intensive paving process that is required to prepare the racing circuit and entire facility for the inaugural 2012 Formula One United States Grand Prix, scheduled for November 16-18.
The massive paving project will involve final paving of the 3.4-mile racing surface, venue access and service roads, and walkways around the property. A paving project this large and complex requires acute attention to detail to ensure the finished surface can accommodate varying weather conditions, as well as high performance vehicles racing at extremely high speeds throughout the year.
Defined as “echelon paving,” the process involves three to four paving machines moving in unison along the racetrack surface to ensure a uniform, seamless top layer of asphalt.
The process and equipment are considered to be highly specialized. One particular instance in which this paving machine is being used is in Central Texas to pave the State Highway 130 extension.
The pavement material itself has a unique composition compared to that used for public roadways. It is required to be highly skid-resistant for the type of vehicles driving on the track, as well as the high speeds being reached. The composition ensures consistency of texture, smoothness of ride, and the conformance to the specifications outlined by motorsports governing body, the Federation Internationale de l’Automobile (FIA).
Approximately 10,500 tons of hot mix asphalt is used to pave the track itself.
The paving process will limit access to on-site visits and interviews. The Circuit of The Americas communications team will work to accommodate media interviews or meetings at its downtown offices during this time.
