Photos – track paving under way at US GP circuit
10 August, 2012
Aug.10 (Apex) Austin’s Circuit of The Americas reached another construction milestone earlier this month, as the the construction crew began laying the final piece of base course and completing 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 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.
