They’re worse in Milwaukee.
the Romans likely used slaves.
The Romans knew better than to build roads in Michigan.
That is asphalt concrete., not portland cement concrete. The cement binder is asphalt, not portland cement.
The relatively thin asphalt concrete surface layer is designed to be replaced at intervals. The whole roadway is several feet thick and is comprised of a series of load bearing and distributing materials. Although the surface in the photo has deteriorated, the underlying road way remains intact.
The traffic and the loads of present day roads can not be logically compared to the Roman roadways.
Portland cement concrete roads are inflexible. The expansion of the inflexible material is accommodated with expansion joints. Over time, the concrete edges at the expansion joints wears away. The result is bumpity bumpity bumpity bumpity bump on an old road. The condition can never be really fixed. Sawing and re pouring the joints fails, paving over with asphalt concrete eventually pushes the asphalt down into the expansion joints with the same bumpity bumpity effect.
The problem you showed is not a design problem but rather a maintenance problem. They delayed the resurfacing too long
To be fair, Rome was not run by liberals...
