Circuit of The Americas hits another major milestone in its construction process with the completion of the third and final layer of pavement around the 3.4-mile course!
The “wearing course” or third layer of asphalt is one of the most unique surfaces in the world. Built with materials from all over Texas, it will allow Formula 1TM racecars to perform at its best. The aggregates that form the asphalt ingredients for Circuit of The Americas have been meticulously selected to meet the standards of the Federation Internationale de l’Automobile (FIA). Oscar Rodriguez from Rodriguez Engineering, one of the subcontractors working on the project, explained how the surface at COTA is not an average one. “The overall design of the asphalt mix for the track is crucial to the performance of the car,” said Rodriguez. ”We work with Tilke and asphalt expert, Dr. Reynard Hart, to produce a mix that is up to their specifications”.
Dr. Hart who works closely with Tilke as a consultant, has paved most of the F1 circuits around the world and his knowledge and expertise was crucial to the overall success of this project. The last minutes of the paving process were crucial and Hart was actively involved with Austin Commercial technicians to make sure the surface was even and the joints of pavement on top of Turn 1 were up to the highest standard.
