i learned a good rule of thumb a while back when testing a concrete, asphalt or stone surfaces.
Take your hand, palm up and place the back of your hand directly on the surface. If you can hold it comfortably for 5 seconds, you can assume that the surface is cool enough for your dog's feet.
I got that from a pamphlet that our local groovy pet store was handing out. It was about the dos and don'ts of dealing with hot weather when pets are involved.
Of course there are always the boots that are specifically for hot weather...
