From Circuit of the AmericasThe final stages of paving the Formula 1 Circuit of the Americas in Austin, Texas are currently underway.
On Thursday, the crew laid final piece of base course and completed the entire first layer of pavement around the track. This process is referred to as “marrying the track" and is taking place from Turn 20, through the starting grid and up the hill to Turn 1.

Unlike building a traditional sports complex like a stadium or ballpark the major portion of construction for Circuit of The Americas is building the “track” itself. About ten feet of Central Texas clay was excavated the entire length of the track.

A black poly material 30 millimeters in thickness was then placed along the length of the excavated portion. This material acts as an envelope for layers of select fill to be placed so that it remains exactly in place.
