No need to be an asshole about it. Some folks probably don't know the relative darkness of asphalt and tarmac.

But according to GP's numbers, tarmac is less dark than asphalt so should get less hot than asphalt. But those numbers are suspect and probably only refer to very fresh asphalt/tarmac; the albedo aka "lightness" of worn asphalt is something like 0.3.
