I would rather have the new asphalt in the corners than the concrete. First off asphalt does not 'cure' as everyone has been referring to it. It cools down and that is it. The reason it was unraveling in the corners is different. And a long winded answer, which I'll spare everyone from unless they really want to hear it. Yes it releases oils for about a year so it should not be sealed prior to that. But concrete does actually cure. It has a chemical reaction that takes up to a 28 days to reach "full" strenght. So if they did put concrete in, they would have to stay off of it with vehicle traffic for at least a week, unless they put an accelerator in it get it to cure faster. But from a rider's stand point I would rather ride over the same material thru the turns as the straights. Different materials have different friction coefficents so the traction is different. Yeah we dealt with it before, but that is part of the reason the track got it's nickname.
I am sure that the track has not sorted out the blame completely yet, but I applaud them for stepping up and fixing it as quickly as they could. With their schedule, I'm sure it was a difficult to pull off w/o bumping anyone, but they managed to do it. Thank you Summit!
