Dead concrete is dead concrete
I'd get it overlaid somewhere between 20 to 40 mm Tarmac, It will work out cheaper that trying to patch and repair it.
Or trying to lay new concrete drive when you consider costs of spoil removal and labour required to lay new sub base and such.
and if you ground is moving under the slab, when the slab been cracked and overlaid it's flexible and will accommodate the movement
