If you truly mean an aggregate driveway - as in gravel or crushed stone - you can just rake or broom some of the surfacing material into the cracks, omitting the stuff that is too big to drop into the crack. Leave about 1/4" high so the tires will pack it in tight, or hammer it in with a hammer or by dropping a sledge hammer on it. Note where the cracks are - if nice and straight look to see if it is an indication of a collapsing drain pipe under the drive.


If you mean an asphalt paved drive, when crack sealing is done by Driveways - Asphalt contractors, as well as specialty companies that advertise doing crack sealing and driveway sealing - google for names advertising driveqay sealing in your area (not an AL category), then cross-check the names you come up with for AL reviews. Most driveway contractors do this type of work.


Note - for a true long-life job you want true hot asphalt sealing (at about 300 degrees, the stuff you seed road crews filling cracks with), not just pouring in some cold oil emulsion like many use as sealer.


For DIY you can buy tar asphalt joint filler (comes in pails and quart bottles. For larger cracks (wider than about the thickness of a half dollar) you can also buy strip tar repair material that you heat with a propane or MAPP torch to melt it into the crack - also available in caulk gun tubes - but a bit expensive if doing more than one or two cracks. Will last a lot longer than the liquid crack filler but a lot more hassle. In either case cover with a 1/4" layer of sand when done to minimize tracking on the driveway, because takes several days to a week to completely cure - and of course avoid walking on during same time, because if picked up on a shoe and then transferred to flooring or deck material can be a real pain to remove and leaves oily stains at best.
