Fingers have been pointed at heavy farm vehicles but these rarely move at
more than 6-8mph and have cleated tyres which tend not to flush water out
of puddles. I believe the cause is car traffic probably travelling at less
than 20mph. Any water standing on the surface is flushed away together
with any grit or fines.


Wouldn't MOT type 3 avoid this?
It has about 30% cavities after compaction so the water drains through.
