Asphalt is a pretty good material for roads, but a very poor one for driveways because asphalt does best when it has a lot of traffic to keep compacting it. A redo with some other material such as concrete, pavers, even stone dust is probably best.

I worked on a blacktopping crew for 2 years. Lotta years ago. We all were agreed we'd never have an assfault driveway.

One crack here and there can be repaired. When it breaks up into a lot of pieces, especially as you have along the edge, it's time to tear it out and replace.
