We did among the repairs final year earlier than MotoGP, so I wouldn’t dispute we’d discover to enact the total factor … Definitely this can additionally involve your full reduction straight, the pit out and allotment of Flip One, there’s a allotment of a gallop earlier than Flip Nine, Turns 18-19. So it’s colorful broad.” https://www.motorsport.com/f1/knowledge/cota-austin-chilly weather-repairs-bumps/4591945/?fbclid=IwAR2Vqb8YZt3ojSfSNIRSqU9iHaK1PIh2TBxM2T0sSR4VBoCq1d7hIj6yhfM&nrt=54
One more article said that Epstein had indicated that factual about 40% of the circuit would in fact be resurfaced. https://www.racefans.acquire/2019/11/04/paddock-diary-united-states-sizable-prix-day-four-2/?fbclid=IwAR0i__RHxVy3P6YXtbwEN5iFicaRguInsOp1wPusBgGs-NTobXL-x3QFcPc The pre-MotoGP restore he’s regarding is a grind and resurface of T10. He additionally talked about that a significant restore is scheduled on drainage constructions that he says discover brought on the bumps and cracking round the circuit.
Many members had been commenting here and in other places that the paunchy length of COTA would be entirely surfaced and/or that these repairs would entail entirely getting rid of the be conscious surface, smoothing & repairing the unfriendly, after which resurfacing it. Neither of these are occurring.
The supreme 2019 be conscious action took situation on December 17 with the Skip Barber Racing College. Around December 19 the first equipment started arriving at COTA … Asphalt Grinders, and dumptrucks to take hang of away what the grinders shaved from the be conscious. A couple of days later, this checklist surfaced, exhibiting broad grinding of the T1 braking zone.
Below are pics from the final week of December, mostly round December 31. The first pic is from u/Senor_Armadillo in r/motogp, earlier in that week. The rest are mine and my buddy’s, on December 30 & 31. They speak areas where the be conscious had been ground round T1 and down toward 2, between T9 and 10, and the reduction straight.

This had all taken situation earlier than December 31, after which nothing took situation for a pair of days. There became no label of any ongoing restore work to medication the considerations with the sub-grade drainage constructions.
Easiest we can show, easiest superficial grinding and re-paving is taking situation, and easiest at T1, T9-10, the Abet Straight, and T18-19. Right here’s in conserving with Epstein’s remarks & the comment about 40% of the circuit being worked on. The most bright areas that had been worked on are the braking zone of T1 correct down to presumably T2. Unsure where that work stops. Then the short stretch between T9 and 10 where that indubitably tough bump is, the reduction straight, and T18 & 19.
These photos are from the day past and at the present time. A sealant coat had been utilized to Flip 1and the reduction stretch, and Turns 18 and 19 appear to had been resurfaced.
