Different how? You think they have separate asphalt plants for roads
versus driveways? I don't think so.

Go to the plant and ask. The only difference here is the aggregate size.
You want smaller aggregate for driveways to match the thinner application.

The only material differences are aggregate size and overall thickness.
But the homeowner can get shabby application (too cool, not enough
compaction, too wavy, too varied in thickness) that a highway engineer
would reject.
