Concrete is a great base material because it is stable and allows for excellent compaction of the asphalt above.
During the winter that moisture freezes and continues to break the concrete down.
Asphalt driveways that are paved over an appropriately compacted subbase will always be superior to asphalt that is laid over an unstable base or concrete that is prone to shifting and expansion.
Asphalt works as a driveway base under concrete only when it is strong stable and at least 2 to 3 inches thick.
When concrete deteriorates it draws and holds moisture.
It will however require a little more maintenance than a typical asphalt overlay.
