The fixes typically settle below under load of vehicles. The reason they are high is to settle down hopefully close to surface level.

They never do! They keeping hoping that happens, but it NEVER happens. Lumps everywhere.

If you're referring to "cold patch" that stuff isn't the same as hot dumped asphalt.
If they replaced a culvert and levelled the pavement properly, now the culvert is a different strengh substrate compared to what was before and after it. It could settle, could heave. If the road isn't made to interstate standards, which is digging down 4-ish feet and putting in the right layers of fill, it's going to suck soon.

They do it on the cheap.

Why did the pothole form in the first place? Is the cause of the original pothole fixed when the hole is patched?
To fix things right involves a cost and time that the public generally doesn't want to pay, so they get patched on the cheap and you get what you get.
Patching a pothole level will result in in a depression shortly after patching. One physically cannot achieve consistently the same levels of subgrade density or pavement density with small patching equipment as is achieved with the original construction and fill width paving. Just look at the size of equipment that is used...
If you guys think you've got a better mousetrap, go invent it and sell it. It will sell like hotcakes...
Also to anyone who thinks they can do better, go pick up a shovel, start working in live traffic, and let me know how it goes...

I would patch it level, let people drive on it and have it sink down, then go back and level it out.

Any idea what a good thickness of bituminous pavement is?
A good hint is that the idea that recoating it after letting it settle will not result in a layer thick enough to work with properly. There is a minimum aggregate size in the mix that must be accommodated.
Also too thick and compaction, particularly with small-scale patching equipment cannot be achieved. Part of why roads are usually built in multiple layers. Multiple inch layers - not fractions of an inch.

They'll repair a street here; it will be great for a few months; then a pothole or trench will appear. They fill it with gravel, but after a few days all the gravel has been scooped out by car and truck tires, so they do it again. Repeat. Eventually (it could be years) they come back and fill it with the cold patch stuff mentioned above, but they never grind it down to the surface level, and so now you bump *up* instead of crashing *down.*
Yes, part of the reason is that there is no "there" here -- it's all floating prairie. Certain high ridges provide a good basis for long-lasting smooth roads, but there are precious few of those.
And don't get me started on why they can't seem to make exits and entrances at parking lots match with the surrounding road. You always end up crashing down or up. I suspect they don't hire experienced engineers and workers; they get some high school dropout, hand him a tool, and say, "Well, see what you can do."
