Last I heard, when a utility company digs a hole in the road they are supposed to put a temporary repair on then revisit it for the final surfacing a few weeks later after the ground has settled. I have no idea if this is still the case.
The quickie repair men repairing small holes etc(literally in minutes) are normally pretty good at levelling because the work is supposed to be inspected and the last thing they want is to have to return to rework the job.
That new skin resurfacing they do is pretty rough but relies on traffic to settle it in over a few weeks, I was highly sceptical of this when I first came across it but had to admit afterwards that it was much better than I thought.
The new partial resurfacing I spotted on Barnston Road around Whitehouse Lane was appalling, basically they had applied small hole repair techniques to a very large area.
I'll keep my eyes out, especially around RLW.
