''Self-Compacting'' Soils | Underground Construction

A vibrating table method of compacting graded crushed stone materials in the laboratory is described. It is shown that maximum dry density of crushed stone, both in the laboratory and during field compaction, is achieved when the material is in a near saturated condition and that the workability of the material is the restricting factor.

How is soil compaction with crushed stone?

Crushed stone bulk density, calculation of the degree of shrinkage. Physico-mechanical properties of slag crushed stone. Bulk density is a value whose coefficient is taken into account during operation. This is the ratio of the volume of crushed stone to its mass, that is, it is its density even before the start of the compaction process.
