compactors are those machines that are used for compacting soils in
various construction projects like roads, highways and buildings. In
soil compacting techniques, energy is applied to loose soil or other
material which increases its density and consequently its load-bearing
capacity. There are certain advantages of soil compacting which are as
- Water seepage is minimized
- Contraction and swelling of soil is reduced to a certain extent.
- Prevents damage from frosts.
- Increases load bearing capacity.
Types of Soil Compactors
For different types of soils, different types of compactors are used.
For example for thin layer of soils, static steel wheel and pneumatic
rollers are used. For cohesive type of soils, impact machines like
jumping jack rammers are applied. For granular soils and asphalt, plate
compactors are applied. Plate compactors are vibratory compactor which
depends upon frequency and amplitude. For soils with greater cohesive
content, machines like vibratory rollers are used which is available in
both single and dual drum models with either smooth or padfoot drums.
Soil compactor plays an important role in many infrastructure projects.
They have their applications in the following areas :
- Soil compactors are useful for compaction in urban areas, roads
- They are also utilized for landfill and paving applications.
- Soil compactors are suitable for compacting mixed soils and
cohesive soils in thin and medium layer thicknesses in large areas.
- They are also applied for landscaping and preparing sites for
- They have their great utility in compaction of soils and gravels
in trenches, around retaining walls and or any other difficult job
