I have a 1/2 mile driveway that I need to do something with.  I was thinking about just adding some gravel, but the person at the quarry said they have recycled .5-1" crushed concrete for $9/ton vs $20/ton.   I haven't worked with it ever and couldn't find much online.
I have a tractor, loader, boxblade and am considering a land plane for spreading and maintaining.   Will a crushed gravel surface allow me to freshen it up with a land plane just like gravel would?   Any downsides to that material from anyone who's used it?
