I remember when major roads like the A34 between Oxford and the M40 were
made up of concrete slabs, with tar expansion joints. Not a nice road
surface to drive on - very hard (tarmac is hard, but there's a bit more
give in it) and the thump-thump-thump of each joint gets very annoying
after a few seconds ;-) About the only thing in their favour was that
concrete roads were very hard-wearing and didn't need resurfacing every
few years.

Unless built on clay with a tendency to "heave".
