Anyone know if this is workable?

Is there any possibility of repairing the MOT1 where needed, rolling
or whacking it, then pouring a binder on/in? Such as cement slurry or
tar. Then adding a tar topcoat to stop rain saturating and freezing.

There's then need to close off road access for curing. Also no need to
but the sand or stone parts of the concrete. A 3rd is far less and
easier mixing.

Now that you mention it, perhaps spraying with tar would be an option. As
long as there is a clean (ie un muddy) top layer, then it will tend to
create a weak tarmac (weak because it won't get fully between the rocks, but
it out to generally bind them).

However, if the OP can't keep MOT down, I'm assuming that the underying
ground is very unstable?

I suppose really the only permanent solution is to dig the road up and
lay enough depth of hardcore and MOT1, roller it, then add tarmac.
Anything less will break up sooner or later. Its a life versus budget
call. Concrete roads do last decades, but there's no chance of
vehicles passing for days.
