-
they are both going to burn your feet but the concrete will release the heat sooner than the black
-
The white concrete surface will cool faster at night, therefore the black ashphalt driveway will be warmer at the end of the day.
-
the asphalt will be warmer. i'm not sure which will cool faster.I assume that the concrete will feel cooler at night because it was cooler in the day.

I saw the black absorbs the heat in the day but will cool faster as the white will retain the heat during the cooling process.
