Factors affecting compaction of soil

 

Soil compaction is affected by many factors, including the type of soil, water content,  soil structure, and compactive effort.

1.   Soil type

Heavy clays, clays, and silts are more resistant to compaction.Sandy soils and coarse-grained or gravelly soils are more easily compacted.

2.   Water content

Water acts as a lubricant, allowing soil particles to move more easily into a denser configuration. As water content increases, the dry density of soil increases.

3.   Soil structure

Compacted soils lack good soil structure, which can limit water entry and restrict plant growth. Air spaces that are essential for water, gases, and plant roots are compressed.

4.   Compactive effort

The type of plant (weight, vibration, number of passes) can affect compaction. For cohesion less soils, vibration or watering are most effective for compaction.

5.   Site conditions

Weather, type of site, and layer thickness can affect compaction.

6.   Admixture

Adding admixtures can change the compaction property of soil.

7.   Permeability

The permeability of a soil depends on the size of voids.

8.   Reinforce soil

Ensuring soil drains well can help prevent compaction.
