I’m not claiming that Americans invented paved roads, but everyone should be able to make them by now. As P.J. said, a few loads of gravel, some sand, and an ox (or the wife and kids) pulling a grader.
Well, the Romans did pretty good - but very, very rough cobbles.
T’was MacAdams of scotland who got the details right” grading, surface and sub-surface drainage, culverts, rock sizes from large to small, top water runoff and culverts ....
