The ground will infact heave where winter is present. Anything on the ground's surface will move. It all may float peacefully. Or it may crack from the heaving. Unless you have frost footers, piers, etc - she's gonna move.
In terms of dry set pavers bedded in sand over concrete.....the heaving most likey wont harm anything.
Rebar and proper use of wire is everything.
Multi-level parking decks are built entirely of concrete and rebar.
In europe most buildings are constructed entirely of concrete and rebar.
But......this does not mean starting next week all my jobs will be placed on a concrete slab. Aggregate bases have their place.
And concrete slabs really are supposed to be installed over an aggregate base. So by the time you install the base for a concrete slab, then pour concrete, you're doing twice the work.
