Which equipment is widely used for compacting clay or granular soils?

The vibratory roller is particularly effective for compacting clay or granular soils due to the dynamic forces it generates during operation. This equipment utilizes vibrational energy to enhance the compaction process by loosening the soil particles and allowing them to settle more tightly together. The vibration helps to overcome the friction between soil particles, achieving a denser packing of the material.

In the case of granular soils, the vibratory action aids in displacing air and moisture, promoting effective density and strength. For clay soils, the vibration helps to break up the cohesive nature of the particles, ensuring thorough compaction and reducing the potential for future settlement or instability.

While the other equipment types mentioned may also be used in certain compaction scenarios, the vibratory roller stands out for its efficiency and effectiveness across a wide range of soil types, particularly when needing to achieve high densities in stiff clays and loose granular materials.
