Rollers Used for Compacting

Roller are used in huge construction projects to compact materials such as sand or soil. They usually have a huge drum which is essential to their design and is what is used for compacting or densifying material. Compact rollers combine static force with hydraulics in order to reduce the size of the soil or any other material.

Rollers are among some of the most well-known equipment and are typically in jobs requiring the surface material to be compacted and smoothened. Although rollers are most commonly used in road construction jobs, they can also be found on agricultural jobs and landfills for compacting materials like gravel, asphalt, or concrete. Rollers are used to turn these materials into perfectly flat surfaces, creating the perfect foundation for the final surface. 

Although there are a few different types of rollers out there, they all share a few common features such as the drum (either a smooth, static one or a vibratory drum), a compaction meter, tires, and a water system. With the help of a roller, you can increase the load-bearing capacity of any surface, which is why they are considered to be an extremely important piece of equipment for construction projects. Rollers are also used in mines to compact or densify soil prior to concrete being poured into them. 

Types of Rollers

A roller can work in two different ways depending on how they were built. A roller that is built without any hydraulics and works without any form of vibration is a static roller. Static rollers work with raw weight and drum-type wheels to densify the soil. 

A vibratory roller, on the other hand, uses both weight and vibration to compact the soil. CAT vibratory rollers are one example that can be spotted commonly working at a job site. The combination of the vibration and weight work well together in increasing the strength of the surface and making it more capable of bearing heavyweights. Vibratory rollers have a drum that provides the force to compact the surface and have mechanisms that create vibrations as the roller moves on the surface. 

Where are Static Rollers Used?

Rollers have huge drums that are used to compact the surface. These drums are either static or vibratory. Static rollers are used mostly on cohesive and clay soils as a vibratory roller would not work well in such a setting.

Where are Vibratory Rollers Used?

The drum on a vibratory roller produces vibrations. These vibrations along with the pressure of the equipment work well in compacting the materials. They are most commonly used to compact granular soils and concrete.

Why is it Important to Compact the Soil?

In order to make the ground more stable and resistant to destruction from water or tree roots, it is necessary to compact soil. Compacting soil will make it possible for it to handle more weight and prevent it from eroding. If a road is not properly compacted, it can sink in areas where the water has penetrated and eroded the soil underneath, so compacting is essential to avoid this outcome.
