30 to 40 years if it's laid properly, and that "if" is doing a lot of work. The tarmac itself isn't really the variable; the base underneath and the edge restraints are what decide whether you're looking at decades or a handful of winters before it starts breaking up at the sides. That's the bit we won't cut corners on, even though it's the bit you can't see once the job's finished.
Walk on it the next day. Give it about three days before driving on it properly, longer in cold weather since it takes longer to fully harden. Try not to do sharp turns or leave a car parked in one spot for the first few weeks, it's still settling.
Barely anything, which is half the appeal. No joints or loose stone to deal with, so it's a sweep and occasional rinse. Deal with oil spills quickly so they don't stain, and keep grass and soil from creeping over the edges — that's usually where problems start, not in the middle of the drive.
Depends what's underneath. If the base is still sound, yes — we can overlay it and you skip the cost and mess of a full dig-out. If the base has actually failed, overlaying just hides the problem for a year or two before it comes back through the new surface, so we'll tell you honestly which situation you're in after we've had a look. Not going to sell you an overlay if it's not going to hold.
