He's being goofy...
--asphalt is classified as a flexible paving material and it will displace under sufficiently heavy loading even if it's been laid over a solid concrete base.
Or at least that's what they taught in tech school back in the late 70's
Very flexible. Near here in hot sunny TX there is a highway overpass that has a left turn lane on a slight downhill slope to a stoplight. When they originally built it that area was asphalt. In the warm weather every car coming to a stop at the light was pushing a small wave of asphalt ahead of it. They eventually tore it up and redid it in concrete.

And, if iggy is tearing it up now, as another says, just wait 'til it warms up this summer--even Chi-town on sunny July day, black asphalt-->gooey.
