The local obscenely named utility company dug in our road a few years ago, necessitating a large patch. They proceeded to drive through their patch as they left. The tire dents & ridges are still there years later. You're right, of course, but I think you may be overestimating the concern patch crews give to their craft.

That's a method in the manual - "roll-and-go". The fact that it's still there years later is actually proof that the patch was effective, if maybe not well applied.

That's ... How you compact a patch.

Anyhow, it doesn't matter how much care they put into the job, if the substrate fails the road fails. Simple as that. Patches are temporary fixes.

Eh, maybe I didn't describe it well. We're talking 1 lane wide, maybe 80 ft long. Dually tire path through the patch. Indented, with the displaced material ridged up along the side, diagonal across the lane. It yanks my motorcycle tire sideways if I hit it, and it's a decent bump in a car. If that's… how you compact it, we need new standards.
