I have never seen edging around here. One of my neighbors has a paved driveway and it looks great.

Oh and make sure the base is about 8-10" wider on each side of than the blacktop edge.
I just checked and there is a lot of discussion on precast driveway edging. A nearby subdivision did not install traditional concrete curbs but precast pieces along the side of the street. The curbing pieces did not fit together but you can buy precast pieces that do interlock.
