3/4" minus is PERFECT for top dressing a driveway..5 to 1 inch is pretty big to get a good finish....as a base, it would work good. If the max was .5", I would jump on it immediately.
Does the concrete have any fines in it? If your using it as a top dressing, it should really have a lot of fines and dust in it to lock in the chunks.
Part of our 1/2 mile drive, on a slight incline, has now lost most of the fines (25 years old) and a bunch of the 1" rocks are now loosening.... talk about a rough ride.... and it's now about impossible to grade it smooth.
I am planning on dropping about 200 tons of 3/4" minus.... about 50% of the mix is 1/4" down to powder. Easy to grade and smooth. Packs in like concrete.
Recycled asphalt is EVEN better!
