my driveway maintance routine has evolved into.

i use my RB3572 rear blade

pass down the middle sq/flat blade set as deep as it will cut (ie 3pt in float)
return home hitting any high spots that need extra attention.

tilt blade to drag material to center, tilt to cut crown.
pass to end and back twice staying wide to cut sholder and drag any lost material back up on top.

set blade to flat and sq, smooth out built up area in center. useually down and back creates the major path that cars use every day.

Total width of drive when i bought the property was about 8', there was plenty of base there, it had just been grown over. It now streches about 12' and have virtually no grass.

My driveway maintance occurs about 2-3 times a year. Late winter on a warm day, middle of spring (these 2 are only a couple of months apart) and later summer early fall.
