Mildly Interesting

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

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.

what is this in normal units

[–] PerogiBoi@lemmy.ca 7 points 1 day ago

Almost 74C!

160F = 71C for the freedom challenged among us.

Seems crazy hot to open up for traffic tho.

They can’t walk

Just wait until it get twice as hot this summer.

Asphalt is laid somewhere around 300F, so if it truly got twice as hot it would melt the road and everyone’s tires.

Well, 0 is arbitrary in Celsius and especially Farenheit, so doubling that temperature isn't really doubling the heat.

Kelvin has its scale actually designed around how heat energy works. 160F is 344K. Double that and you've got 688K. Convert that back to stupid-units and you have 779°F

I think I did that right, at least. If nothing else it shows how whacky temperature math can be when doubling units gets wildly different results!

Hey, hey, that’s freedom-units to you.

That said, the difference in scales when it comes to doubling is something I never really considered. Very informative!

Used to be a paver and I can confirm that shit is HOT, only gets worse once you hit it with water. The steam will give you blisters as you work it

Op get data!

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

I just touch the pavement with my hands every time the road surface changes. If I can't hold it there comfortably for a few seconds my dog is not going on it.

Topdon. I had Flir before and like this much better. For one thing, they don't watermark my images.
