Can you apply concrete onto existing concrete that has chipped away (a driveway)? Our driveway is slowly crumpling, can I just clean it up and top it up with concrete?

Simply cleaning it up and "topping it with concrete" may work for a while but it will not solve the issue. Your best bet is to chip/cut away the parts of the driveway that are crumbling away. Go all the way down to the ground. Chip it all out and then pour new concrete. This will last alot longer than just topping old concrete.

Concrete that is crumbling or chipping is usually conducive to improperly batched concrete (too much water, too much sand, steel reinforcement too close to the surface or ground) however in some instances resurfacing your concrete can be a viable alternative.
First you'll need to clean the area with muratic acid, then apply a primer such as Brickform overlay primer then mix an overlay material such as Brickform Stampable Overlay that has 50% water - 50% liquid polymer (yes, we use Brickform polymer too!) -this mixture has proven to be quite successful for us! ( we resurface concrete slabs daily throughout the USA

If there is some outside force (roots,etc) causing the driveway to chip/crumble you have to remove.
Otherwise just put a good topping on it. Every inch you add to concrete makes it exponentially stronger.

You can; they make resurfacing products, but bear in mind that what caused the original problem will still be there. And remember that driveways take a heavy load. It will get worse.
Best to remove it, build a form with footings and rebar and pour a new one.

most toppings are a tempoary fix... any cracks in the old concrete will enentually telegraph through to the new stuff...if the top is just spalling you can use a bonding agent and top it but even this wont last forever...if its bad i would replace it...

yeah, you could do it the way you said, I suppose. Did you want it done WELL THOUGH? How much more would it cost to just completely redo it?
