Soil compaction - Wikipedia

In geotechnical engineering, soil compaction is the process in which stress is applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred.

1. Introduction. Many soils contain varying horizon-specific amounts of gravel. A data-set by Batjes (1997) based on FAO–UNESCO soil units includes C-class (6–15 vol.%) gravel content levels for phaeozems and yermosols, M-class (16–40 vol.%) gravel content levels for lithosols, regosols and rankers as well as A-class (> 41 vol.%) gravel content levels for rendzinas.
