Concrete driveway expansion joint repair/replacement

[Darrell Walker <darrellw@ipns.com>]

The expansion joints in my concrete driveway (about 15 years old) are 
rotting away (they are cedar boards, and I'm in the Pacific NW).  Any 
ideas on how to repair/replace these?  I could get the rotten wood and 
accumulated dirt out, but I'm not sure if I could drive another board 
in place.
