The question pretty much sums it up. How TF is the asphalt 20-40° hotter than the air when it’s super hot?

Very basic grade school explanation: dark color absorbs more heat as does matte/textured surfaces both of which apply to asphalt and such surfaces. Smooth=reflects light. White=reflects light. Remember white=all colors of the spectrum. This is also why we’re told to wear white on a hot day. Black= no color so absorbs all rays from spectrum. Black=absorbs light, textured surface= absorbs light. Source: I’m a teacher who has taught 8th grade optics.
