WxLover16, I suspect that you will see a difference with the asphalt surface. I believe the asphalt will absorb much more heat than the lighter colored concrete and transmit that heat to the concrete below it. The lighter colored concrete was reflecting more solar radiation than the black asphalt will...thus the asphalt will absorb more energy and what it absorbs it will give back. My thought is that you will see a slower cool-down after the sun goes down. Being only 10' from the street, seems to me, would cause gentle breezes blowing over the asphalt toward the ISS to affect readings, but these were already affected by the concrete so it's not like you're going from grass to a more solid surface. Something else, and I don't know if it's correct (or anything else that I've mentioned, either, as far as that goes
) but asphalt, usually manufactured from petroleum has an oily consistency and to me "seems" to get hotter than concrete...think of walking barefoot and having to hotfoot it across the pavement until you got to the cement sidewalk...something about that oil...??? How much asphalt did they put down...1", 2", 3",...?
It will be interesting to see how your long term data compares with your past data.
Best wishes.
