No form of connection directly to the concrete will give you any additional 
radial length or ability to dissipate any currents. You would need a low 
impedance connection to any( a lot of driveways don't have rebar or mesh 
reinforcing in them) metallic items in the original pour. Your really out of 
luck on existing slabs. Prestressed slabs are a whole new category and not 
really pertinent to this thread but usually have some method of grounding any 
structural steel contained, and sometime cathodic protection for tendons. Most 
antenna radials are part of the antenna tuning and therefore need to be a tuned 
length to be as effective as possible. Again that is another thread that the 
group may want to rehash again.:-)
  So put that box of concrete anchors away and get out the antenna analyzer to 
tune radials. Then you can sit back and enjoy your new concrete work!
