Getting nearer my concrete driveway project, and I'm repondering mix
details.

It Appears that readymix PAV2 concrete et al includes an air entraining
additive to make micro bubbles in the set concrete, these supposedly
increase protection of the concrete from freeze/thaw cycles of future
winters...

I'm mixing my own 5 ballast to 1 cement.

Is standard mortar frost proofer suitable ? Or something else?

I wouldn't bother. I've never used frost proofer in concrete and
haven't any experience of subsequent problems.
