I've done loads of work on a solid (either lean mix or base tarmac) sub base when I was doing the commercial work Tony.
If it rains before the area your laying is finished it's a pain because it takes longer for the bedding layer to dry out so it can be days on end before you get any kds in the joints and compacted.
On a personal note I prefer laying 50's to 80's. I'm sure my arms are 100mm longer than they were when I was 16 due to laying them feckin things. Especially 80mm tegs.
I've never used any recycled materials as a sub base, not even crushed concrete. I get good millwaste for a few £ more than crush so I can't see the point. I have used a lot of recycled glass for bedding and much prefer it to sharp sand as I find it compacts much better.
