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.

Long story... this lane may date back to Roman times and apart from
agricultural access was used to reach gravel and hoggin on the high
ground. Narrow lane, hoggin surface and reasonable fall to drain surface
water to river.

Come the village by-pass! Because of the river valley, much of the new
road is on an embankment. Embankments cost money as do bridges capable
of taking dairy cows and combine harvesters. The upshot was that the
lane was *lowered* to provide space (3m) for farm traffic and the lane
fall reduced to something like 1:200 or none at all if the river happens
to flood!

The consequence is that the underlying soil is wet for most of the
Winter and the holes are permanent puddles. If I were trying to cart
regular straw bales at 40kph this might be a problem but you can't get
many rings of bales under a 3m bridge and I don't have any tractors
capable of such speeds:-)
