How is the track looking Austin? Any further deterioration?
The last time I was out there was in April for MotoGP. It looks worse by varying amounts every time I go. Since then, we had a cool, very wet spring that suddenly got very hot and very dry in July & has stayed very dry since. That's probably not good & will probably have caused even more movement of the soil. I've read some comments recently from track day attendees complaining that the bumps are just getting worse and worse.
Here are some examples of what I saw in April. There are plenty more like these. Notice the lighter areas where the track has been 'shaved' or ground down to smooth out bumps. Every time I go out there, there are new areas that have been ground. They're all over the place, and they also tend to be where the cracks are worst and most frequent. Asphalt guys on another forum (and I think maybe here as well?) predicted this when COTA started bump grinding operations.
In this picture (around t5 iirc) you can see some kind of sealant has been used on the cracks. These were the first cracks that appeared before F1 2018 iirc. Remember when the FOM guys opened FP1 with a close up shot of them? As of April, these were the only cracks that had been attended to. These cracks will only worsen if not repaired.
The infamous T2 bumps ...
Notice the rider's line here. Earlier in the day on Friday they were taking a wider line to avoid the bad bump on the inside of T18 that wrecked Vinales. That put them in that area where the track is deteriorating. The riders all adjusted to the inside line to avoid it, just as they've had to adjust to the outside of the T18 apex, where normally they'd come within inches of the kerb. That left them threading the needle between the bump and the breakup.
