Its interesting to note the regional variations.
Around here the typical application seems to be to spray a coating of hot liquid asphalt/bitumen down on the old paving, then a dump truck dumps a line of fine gravel which is spread over the road surface. Sometimes it is spread pretty evenly, sometimes its very uneven with long piles of loose gravel which are quite nasty.
I've seen the style with the overspray as well, but that seems to be done for only very short patches, or people private driveways. I really hate that as you get tar and gravel splattered up on your vehicles when it is fresh.
