The problems associated with poorly constructed driveways tend to originate from builders not preparing the surface of the subsoil with aggregates to allow for free drainage of water, not understanding the flow of water over the surface area or water undermining the structure by not installing sufficient drainage. Unless the driveway is laid on free draining soil, stone chipping should never be considered and only if the land is flat and the subsoil has been prepared using aggregates.
If a concrete base is laid as a foundation, again the subsoil should always be prepared first. Reinforced concrete that maintains and gives structural strength by using rebars is the general rule.
The above issues can undermine the structural integrity of the driveway and lead to cracking, subsidence and buckling of the surface area.
