It seems that in wet weather many suffer due to a vehicle going off the
tarmac and making a rutt in the adjacent earth. This then leads to the
tarmac crumbling away into the rutt and so it continues.

In my mind I can envisage a machine that could excavate a narrow trench at
the edge of the tarmac that could be followed up with some steel stakes and
reinforcement and then a readymix lorry.

Has anyone seen any solutions that work that are not as major as curbs?

The problem has arisen by satnavs sending heavy vehicles down roads they would never find in the past.

It's even worse if there's a gradient, rainwater washes the ruts out.
