The Circuit of the America's racetrack passed an inspection on Tuesday which paves the way for it to host an F1 race in November.
While there were still construction crews at the race track, enough of the facility was finished so that the inspection could take place. Charlie Whiting, an inspector with the body that oversees international motor sports, FIA, approved the track.
Last week the final layer of asphalt was poured onto the 3.4 mile track. It's a specialized mixture designed for high speed. The paving process took almost 4 months to complete.
There are three different layers to the track. The first layer, or base course, is meant to support the vertical forces of the cars. The second layer, or binder course, is designed to support the horizontal forces of the cars during acceleration and breaking. The final layer, or wearing course, is meant to provide grip at high speeds.
Whiting's inspection tour lasted two hours. During his walk he focused on safety and technical aspects of the surface. He told FOX 7 a to-do list is being left for the contractor.
"Not so much tweaked, we've just got a few details to to go through some fine detail on some curbs we just need to be clear about," Whiting explained. "That's got to be done in the next week or two, it won't be a very big list."
He said nothing on the list will prevent the race from being held.
There's still a lot that has to be done before race day, like installing the lighting in the parking lots and also taking care of all the landscaping. A major focal point will be the observation tower and amphitheater at the center of the track.
Despite all the construction that is still ongoing, track officials are confident all will be ready for the November race. Whiting said he would also be back before the flag drops for one final review.
