Generally, for driving on, a 3-4 inch asphalt drive will handle it, as will a 4-5" reinforced concrete drive - IF the subgrade and base are properly compacted and well-drained. In poorer soils a 5-6 inch thickness may be needed, though thickness is no replacement for proper subgrade prep and excellent compaction.


Whether your existing concrete damage is due to poor subgrade conditions, too thin a concrete slab, freeze-thaw action or what I can't hazard a guess to - though it the slabs are tilting or offset at the joints then the subgrade and/or base material are at least partly to blame.


Pavers - I would not recommend for driving/parking an RV on - you WILL get some tilting and dislodging or breaking over time.


For PARKING on, unless you put the wheels up on good wood blocking (commonly 2"x10"x36" or larger) you WILL get wheel/jack indendations in the asphalt over time - so for the PARKING pad, if wheel indents are an issue to you and you don't want to mess around with placing and driving up onto wood pads each time, concrete or a crushed stone (driveway base material) pad is the usual solution. Personally, I recommend crushed stone pads if allowed in your area - spending a lot of money on paving just to park an RV on top of it makes no snese to me. A bit of Roundup will keep it weed-free - though a 4-6 inch stone pad will stay fairly weed free anyway except at the edges.
