Our drive is roughly 500 feet and is asphalt. About 35 years old and still in pretty good shape. If you go with asphalt, get a very reputable contractor. I've seen some bad results with the cheap ones.
If you are pouring anything wider than 3 feet this is a smart idea. PVC is cheap compared to ripping things up or having to work around them. Even if you put one 6 inch in the middle that you can run multiple things through if needed.I haven’t seen this mentioned but when I used to do drive lanes, both asphalt and concrete, I’d install 2” Sch 40 pvc sleeves intermittently across the drive.
You can install a pull string and leave a length buried out each end.
That way you in the future you can run electrical, water or other utilities under the drive.
Just be sure you have a good set of ‘As-Builts’ so you know where they are at.
