You can't really repair a concrete drive that is breaking up.

It is doing it for probably 2 reasons:

1. the concrete is poor quality

2. the base underneath is poor and moving

the only way to sort these problems is to dig it out and start again properly

Not strictly true. You can repair concrete with a resin injection, but i agree that unless you know the cause of the problem, you could end up with a resin drive after a period of time, costing more than it would to replace the whole lot.

If its deep cracks dig it up or kango it, tamp it and re concrete.
If its just surface crumbling as I have brush off, remove all loose stud, re skim

yes there is Exopy based resins...two problems with them, price (Horendous), and tend to be stronger than the concrete, and the concrete just continuaes to break up.

Far better bite the bullet lift what you got and redo (Bet that's the answer you didn't want)

You could protentially bodge it and put more concrete over the top usually bad idea, just adds the the mass wanting to break up, and often if against house will bring leval of conrete above that of the damp course (very bad)
