An idea worthy of study. I would like to see a few miles built to test.
However, there is a LOT more to a road structure than the surface.
The glass surface could replace only a tiny fraction of the petroleum,
portland cement, lime, etc that goes into making a road suitable for
heavy traffic. Most road failures begin with failure far below the
surface. Having a very durable surface will not prevent road failure.
As Lee notes, a PV surface would greatly complicate inevitable road repair.
