Why would you want to think about it that much ?
There is a lot of heat escaping from the truck while it is waiting to be dumped and this creates temperature gradient inside the load. I didn’t have to think about it that much because I worked for many years in asphalt surveillance.
Normally we don’t use infrared cameras but we do have infrared heat guns and much more sophisticated devices.

i gave only the basics. From those I could explain the pattern or someone could think about it very hard and understand how the pattern is created.

Lol, no. Tires momentarily contacting hot asphalt while rolling on it will not significantly lower the surface temperature of hot asphalt. The road paving process produces T⁰ unevenness while spreading asphalt … notably because of flow of asphal from the uneven T⁰ in truck loads waiting typically 1 hour before being dumped … then carateristincs of flow in the paving machine … and … civil ing. … whatever.

“… you could find much cheaper and simpler solutions…”

Heat feelt thanks for your bold show of confidence in my technical capacities. Yet I have to disclose that I’m not exactly sure to be able to compete with a first world power like China.

This is a useless advertisement of mentally ill persons’ delusions. Whoever that person is, that advertisement is still useless - - both for us and everyone else.

the programming language “Rust” is being used more to make new Linux kernels. Traditionally, the main language for that use was the one by the name “c”.

… i am surprised, i expected the figures to be in the thousands 🤣

We have a physicist here ! Thanks to the universe 😁
