3/4 Inch Crushed Stone | ASTM 57 Stone – How to Hardscape
3/4 Crushed Stone. 3/4 inch crushed stone is a useful aggregate in several applications of hardscaping and has become increasingly relied upon in permeable and open graded base installations where the water that enters the system is meant to freely drain through the base material and penetrate into the subsoil or be collected into a drainage system and exfiltrated out of the system.

How much volume is lost after compacting 3/4" crushed stone?
The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4" stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to of some form of "proctor density", because you're awesome at compacting and have a monster machine (and thin lifts), that's 100/80=125%.

Crushed Stone - an overview | ScienceDirect Topics
Boreholes were drilled to examine the depth of the crushed stones after soil improvement. One of the borehole logs is shown in Fig. 18.8.The stones were found to be present up to 9 m, in which the top 5 or 6 m was densely packed, whereas the remaining 4 or 5 m was embedded in clay.Below the crushed stone layer were a silty gravel layer and the weathered sandstone layer.
