How much volume is lost after compacting 3/4" crushed stone?

If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.) If you use a jumping jack, about 20% would be accurate.

Factors affecting Compaction of Soil Types of soil

Mar 10, 2019 Factors affecting Compaction of soil. Compaction of the soil is the process where the dry density of soil is increased by reducing air content or air voids present in the soil. This process is an essential part of the construction of any structure, as it strengthens the soil. Many factors influence the degree with which the soil is compacted.
