The Circuit of the Americas has completed the track pavement with success. Yesterday workers completed the third and final layer of asphalt around the 3.4 mile long circuit. According to the circuit the last layer on the track is unique in the world.

The ingredients for the last layer have been meticulously selected to meet the standards of the Federation Internationale de l’Automobile (FIA). One of the subcontractors, Oscar Rodriguez from Rodriguez Engineering, explained why this is such a unique asphalt layer.

“The overall design of the asphalt mix for the track is crucial to the performance of the car,” said Rodriguez, adding, ”We work with Tilke and asphalt expert, Dr. Reynard Hart, to produce a mix that is up to their specifications.”

The circuit, designed by German Hermann Tilke, is now nearing its completion and then will be ready for the final inspection by the FIA, just in time for the U.S. Grand Prix on November 18, the penultimate round of the 2012 FIA Formula One World Championship.

Tilke engineers Oliver Liedgens and Frank Both have been supervising the whole process of laying the track, and they are proud of what they and the American builders have accomplished in just two years.

“When we came to Austin a little over 2 years ago, we came to the site for the first time and all we saw was mud and trees,” Liedgens and Both said. “It was really hard to imagine that a track would sit on this piece of land and the only source of imagery that we had was a couple of renders. Today is the first time we get to see the final product and this makes us very happy.”
