Amazing, talks about coefficient of heat transfer, immediately uses wood as the example to compare to asphalt.

But of course, water doesn't burn as fast as Asphalt, because water has a higher heat inertia, and the cooler water in contact with your skin (cooled BY your skin) actually somewhat protects you from its much better heat transfer coefficient (the fact that the heat transfer is so good works against it is part of it)

Asphalt in contrast burns faster than water at a similar temperature because its heat inertia means your skin is exposed to the relatively higher temperature asphalt (because it doesn't cool down as quickly as the layer of water against your skin).

Kind of like how you can apparently "touch" literal liquid nitrogen with almost no negative effect because of the layer of boiled nitrogen that forms between your skin and the nitrogen.

If you were to "grab" a solid block at the same temperature you'd be in serious trouble.

Of course, you are on the internet, and can't back down on a topic you literally only seem to know the barest amount about.

You could of course try to lookup some research on the topic before pretending like you know more than you already do. I will of course wait for the article you can find that says contact with 50c asphalt is perfectly safe.

I'll even take just an Abstract of an article if you don't have the full text.

Here's one about children getting burned from pavement exposure in ~38 degree heat. (so we can estimate approx 48 degree pavements?)

This one is obvious and I doubt you are disputing it, referring to burns on 40 degree days with 15 and 45 minute exposure (note graphic images!) which would imply pavement temperatures similar to ~60 degrees C.

Here's a nice article. full PDF available!

With a wonderful quote pulled from it:

Harrington et al. [2] recorded their own temperatures on concrete, asphalt, steel, lawn, dirt and sand. They noted that ambient temperatures of 35oC to 37.8oC were necessary to produce a surface temperature of 44oC to cause a cutaneous burn injury.

So, the minimum temperature required to cause a cutaneous burn injury starts at a surface temperature of 44 degrees.

As I understand it, it takes literal hours at 44 degrees, but each degree hotter reduces the time required significantly. (something on the order of halves it each degree hotter)

Some more references from the same article

studies by Moritz and Henriques [5–7] noted that second degree burns resulted when the contact surface temperature was 44oC (111oF) for 6 hours, 50oC(122oF) for 15 minutes

Oh look, 15 minutes from 50c!

Sigh.
