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.

Self Compacting Soil (#57 stone) - Eng-Tips Forums
The #57 stone develops good density, (compaction), from free fall due to the many sizes available for each size void. With no compactive effort, a density of over 85%, (very limited settlement possibility) can be achieved with little excess horizontal pressure on the backfilled wall which can come from compaction energy.

Swell Factors for Various Soils - ProjectEngineer
A cubic yard of earth measured in its natural position swells to more than a cubic yard after it is excavated. This occurs because of an increase in voids. Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30%. The following table lists swell factors ...

Compaction Factor Test of Concrete - Expert Civil
The compaction factor is calculated by the formula: CF = ( W 2 − W 1) ( W 3 − W 1) Relation between compaction factor and workability If the concrete has a compaction factor of 0.85, then it represents a mix of poor workability. If it has a 0.95 compaction factor then it represents medium workability and 0.95 represents good workability.

Soil Compaction: Methods, Meaning, and Effects
Soil compaction is the practice of applying mechanical compactive effort to densify a soil by reducing the void space between soil particles. Compaction occurs when particles are pressed together to reduce the space between them. Highly compacted soils contain very few spaces resulting in soil with higher unit weight.

What is compaction? Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively move water downward through ...
