It's amazing what these council wallahs actually do in their eight hours!!!

This is a new olympic sport, hopscotch-bingo.

...having worked a bit with the road traffic engineers it's possible that the numbers are plotted onto a map before they're given to any contractor, who is employed to carry out road repairs...
..it makes it less easy for the contractor to 'miss' any because they 'couldn't see the fault' or 'didn't think it necessary' to fix...
....it also makes it easier for any fault to be recognized by the utilities companies who may have dug up a road and then re-tarmaced in a substandard way (if a utilities company does dig up a road then any repairs to that section of road become the responsibility of that utility company for a certain time limit)

Very true. A spread sheet is usually prepared with reference numbers, square area and details of finish, wearing course and base course thicknesses with the all important compaction procedure, weight, duration and number of passes.
A map/plan of the patches is only sketched rather than measured as all the info is on the spread sheet.
Large scale mapping is not normally available of C class minor roads, so chainages from salient points might accompany the reference numbers.
Contractors are pretty cute and often try to minimise on materials etc. This is where a clerk of works or inspector comes in.
Often, original construction thicknesses are not on record, so when excavation commences, an agreement is made between clerk and contractor and the rate is adjsted accordingly.
