What asphalt millings are
When a road or lot is resurfaced, a milling machine grinds off the top layer of old asphalt. What comes off is a coarse mix of stone and old binder, a bit like dark gravel. Because it still carries some of its original asphalt, millings pack down tighter than plain gravel when they are compacted, and in summer heat the binder softens enough to help the pieces stick together. That makes them popular for long drives and work yards where full paving would be expensive.
Where millings make sense
Millings suit long rural drives, equipment and boat parking, overflow parking at churches and event spaces, and access roads where looks matter less than cost. They are also a sound base layer under a future paved surface. They are a poor fit for short, steep or heavily used driveways next to the house, where loose pieces get tracked inside and turning tires dig ruts.

Laying millings so they hold
The same rules apply as for any driveway: drainage and base first. The ground is graded so water runs off, with a slight crown down the middle of a long drive. On soft clay, a layer of stabilizing fabric under the millings keeps them from being pushed down into the mud after a wet week. Millings then go down in layers of about three to four inches, each one rolled hard, ideally on a warm day when the binder helps them lock together. Expect to regrade and top up low spots now and then, especially after the first rainy season.
Millings or a paved driveway
Millings cost less up front, but they never become a smooth, sealed surface. Loose pieces migrate, edges spread into the lawn, and they cannot be sealcoated like pavement. A tar and chip driveway sits between the two in cost and finish, and a paved asphalt driveway is the cleanest and lowest-upkeep option.
