I could feel the heat coming off it when I stood next to the repaved section. They didn't repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.
160F = 71C for the freedom challenged among us.
Seems crazy hot to open up for traffic tho.
As a kid I burned the bottom of my foot (enough to cause blistering) on fresh blacktop in Palm Springs. They had just opened the repaved parking lot in the full SoCal summer heat when we pulled in to go to the bank. I took 2 steps: the first adhered my flip-flip firmly to the asphalt and the second took my foot out of said flip-flop and landed it right on crazy hot and sticky surface.
Even though this article says that tire rubber starts to break down and melt between 100⁰C to 150⁰C, depending on the rubber compound, I'd still prefer to protect my tires from such high temperatures..

Edit: Those temperatures are also rather dangerous for electric vehicle batteries, which are located right under the vehicle in very close proximity to the road heat.
Geez I hope they put up no pet signs. Would hate for someone to let their dog walk on this.
Since summer is coming in many parts of the world, I'll include a psa about asphalt temps being well above air temps. Good chance if you are enough of a nerd to be on Lemmy you have a laser thermo probe somewhere. Consider bringing on your walk and checking some pavement temps. Avoid walking dog if >115f 46C
Just wait until it get twice as hot this summer.
what is this in normal units
Neat, you can also see where people's tyres have absorbed some of the heat.
Fluke camera?
Hmm, that's interesting. Don't you guys generally use concrete for paving in the US? In building construction, you're supposed to give concrete like a month to fully harden, even though it already looks firm after a day or so.
For paving, they're likely using a hardening accelerator, so the timelines wouldn't be the same, but if building construction is anything to go by, it seems like you'd want to give it as much time as possible, not send cars on there while it's still hot. 🥴
Yeah wtf, that's bonkers.
Ambient temp seems to be roughly 75... maybe wait till it gets down to 95, 90?
