Same around here in Derbyshire, I thought it strange that several weeks before the council were patching up a particular road with real tarmac the reason became clear when it was then all tarred and gritted over.
This is an excuse for a road resurface,cheap and nasty.
The very same county council (Derbyshire) have also taken to erecting illuminated traffic activated 30 MPH signs all over the county at some cost I would imagine while in the very same week 50 school crossing patrols are being axed.
