  • Compaction Geotechnical engineering general discussion

    Aug 27, 2009· Clean 1 1/2 crushed stone does not require compaction. It is spread, tamped in aproxximately 12-18 inch lifts with a plate compactor or a backhoe bucket. Resulting base is quite stong. 1 1/2 can be difficult to place by hand 3/4 is easier to handle. Also if you use 1/12 for the base, raking in some 3/4 stone on top will give nice finished surface.
