Deep holes are drilled in the rock and filled with dynamite, then the rock is blasted. Some of the large pieces that break off are kept for projects like creating rock walls or building seawalls. Most of the pieces are loaded into a machine that crushes them into smaller pieces. The pieces are sorted by using screens with different sizes of holes.

Crushed stone is a type of medium-sized gravel that is formed by mechanically crushing stone. Most commonly, limestone, dolomite, or granite is crushed to form the crushed stone. In certain definitions of the term, crushed stone is not considered gravel since it is a processed rather than naturally-occurring rock fragment.

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.
