Would it even work? Mine is pretty old. A few "pot holes". Most is not bad for the age. I really like having the concrete with motorcycles. But it does need some attention.

Chances are these slabs weren't poured over an unstable base, but rather, frost heaving moved them.
Each individual slab can move at the expansion joints, and if you have an unstable base, the condition can occur more often. A concrete pavement that moves will damage any asphalt overlay over time. If you are looking to add asphalt over concrete, you will need to make sure you have a stable concrete surface below, with no expannsion joint shifting, to make a proper base for overlay. Concrete has expansion joints where asphalt does not.
Over time, the expansion joints will shift the concrete surface and wherever your concrete has a crack, the asphalt will eventually crack there as well. The expansion joint in the concrete is a designed area to allow for a crack, and while there are special reinforcing fabric strips that can be applied prior to overlay, over time, there is a very good chance that the cracks will eventually crack in the same spot on the asphalt.
This is not considered pavement failure, but it is just a result of ongoing heat and cold expanding and contracting. Regular maintenance of your asphalt driveway or parking lot , and crackfilling these reflective cracks to prevent water intrusion will leave you with pavement that will last a long time.
