My neighbor is having his asphalt driveway re-done. His old driveway was full of cracks, and he assumed that the cracks were from freezing and thawing and that probably the foundation under the asphalt was poor or non-existent. Surprise! When they went to remove the old asphalt, they discovered that there was a second layer of asphalt underneath. And, it had absolutely no cracks whatsoever.
So, my question is - what would cause the top layer to crack in this situation? Poor asphalt mix?
I am really curious.
Thanks
