How much will road base compact?

If you use a plate compactor, make sure you don't compact all your base stone at once. You'll get better compaction if you do it in 'lifts' of 2-3". Keep adding base and compacting until you get to your 4" thickness. I get about 5/8" compaction in 1.25" of sand; I use 1" heavy duty electrical conduit to screed (1.25" o.d.), and I use pavers ...

if you still want to be able to measure and document the amount of compaction, you could use the relative density method - see ASTM D4253-93(1996) and ASTM D4254-91(1996) which uses a vibrating table to measure the maximum index density and the minimum density of the material and then determine the relative density of the in …

Stone % compaction | Contractor Talk

You could definitely get compaction placing in 4" 0r 6" lifts. In a confined area wouldn't a ca-7, open graded, angular, washed stone give the same results with no compactions. compaction I think means having no voids after compaction, but if the fill cannot shift ( it is confined by foundation) or settle why would it be neccesarry.
