Crap. So asphalt's emissions actually exceed the gasoline burned by motor vehicles? Maybe making petroleum a major ingredient in our roadways was a dumb idea all along....
I don’t think there are any good substitutes to asphalt concrete for paving roads. Railroad tracks only need crushed rock - if we fully transition away from crude oil, we might have no choice but to switch to rail for all our ground-based transportation needs.
