In concrete, the "seam" just allows the slab to float-sections will be separated by wood or plastic spacers that keep a crack in one area from traveling to the next.

Asphalt is more flexible - you have to make sure that enough material is put into the fix, because it will slowly compact after a while. Also, the sealer that is used to fix the patch along the edges may make the repair obvious. Some people are very interested in the way the house looks from the street,

After the fix you can 'repaint' the whole driveway to make it look new and to hide the fact that a repair was made.
