Swell Factors for Various Soils
Swell Factors for Various Soils. 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%.

Compaction Equipment and Methods: Compaction of Gravel and
Compaction itself is basically the action of applying a downward force for consolidation, taking larger and smaller materials and letting them fall and work their way into place. There is a risk of over compaction as you could, especially with larger gravel, break the granules down into smaller pieces and destroying the composition of that gravel.
