As was mentioned prior, lots of variables. How was the substrate prepared, loose sand, tamped sand, poured over dirt... All depends on the builder and subs how it was done. Sometimes will scrimp on the concrete in the mix and have found that you have to verify they are delivering what you thought you were getting. Most concrete companies are okay, but builders can tell you one thing and order a cheaper mix with less strength. I won't park on my drive, as I wouldn't be surprised that there are voids underneath and places with less than 4 inches of concrete. Of course, it makes it easier as driveway isn't long enough so it sits in the street when I'm loading and unloading.
