I think they're saying 2 inches is fine, 4 is overkill, what you really want to be looking over the engineer's shoulder about are the specs for the setting bed and the bidder qualifications so you'll get someone to do it right.

3" rock dust; (with fines) or rock dust and hydraulic lime wet to the
consistency of beach sand but
for heavy traffic areas (working surfaces )

This is nice, but my question was how thick the slabs should be? Or are you
saying it doesn't matter? Which makes no sense to me.
