So ... re: the track 'weeping' at Turn 10 that we noticed a couple of weeks ago. It's not in the area that's been most recently resurfaced. It's coming from the 'seam' where the 14 month old T10 resurfacing meets the original pavement. Before this latest resurfacing, you could also see weeping from cracks in the middle of the track, on the hill between T1 and T2, in the original 8+ year old asphalt. There was no camera shot of that area Wednesday, so I'm not sure if it's weeping there again yet, but it will. It's a drainage problem & is going to happen wherever there is an opening, & there are already cracks in the new resurfacing going up T1 and at the apex. Guys who have worked there say they had to pump out the french drains daily for a while after rains, and that whenever it's wet & that isn't done, this is what happens. There seemed to be perpetual puddles & wet spots yesterday anywhere old pavement met new, and all along the new pavement to a lesser extent. They just never dried up, all day, even hours after the old pavement had completely dried.
Here's a screenshot of T10 Wednesday afternoon. Look just above the sign support, on the right. That's not one of the puddles I was referring to. That's a steep slope. It's water coming up from below the track, weeping out between original asphalt & the 14 month old section of asphalt. That year-old section of paving starts just before 10 and ends just below it, right where the weeping starts.
Hadn't noticed this until this test, but you can also see on that section of pavement that they've already had to do grinding on it, probably during the 2019 USGP weekend, when it was less than 1 year old.
