The right materials on a solid base a road will last forever, just as roman roads, aquaducts, and other structures are still in use today. Stone doesn't wear all that much, and the concrete the romans used, is still in use now.
Now as far as putting pipes and electrical lines, I would do all of that right the first time, and or leave a tunnel you could change them out in if you have to.
It would be a good use of borrowed money for a change, to build roads that last, as it will save money in the long run in not having to redo them all the time. It would be an even better use of borrowed money to build more freight and passenger rail, especially interstate, but we can't have nice things I guess the plutocracy is dug into how things are now. We pay more money for less and worse things because people profit off of the way we do it now.
Roman roads did several layers, gravel, and the like, to make sure there was drainage and it was on a solid footing, then they would lock in paving stones with sand trapped around it, the sand has no where to go, same way patios are done in a way, and it lasts forever when it's done right. They could even make a solid base with a layer that could be changed every once and a while.
Or even better, although this is out there, is make the roads of some kind of cast ceramic with magnatism in there, and build cars to float on the roads with magnatism. That would take all new cars and or drivers to make them compatible, but would be way faster and more efficient.
