Thanks Streetcar, that seems to be the consensus..
Rework and compact it like regular gravel driveway
When I had millinggs, I'd use my Yanmar PTO rototiller to loosen it up running in reverse, then use my 8' York rake to smooth and crown it. Only problem is that now you have a superhighway, so teens, delivery drivers and neighbors coming over run at high speed. Couple of well place 2x4 in then solved THAT problem.
Had a similar issue but it was rutting as opposed to washbaording.
We used a pulverizer on it and that worked great. Every few years we added a maintenance layer to it as well.
