Familiarizing With The Road Roller

There are several types of road rollers, each with its own applications. Understanding the type of roller and how it works informs decisions on which is best for the project. There are two main classes of rollers; vibratory rollers and static rollers.

Static road rollers

This type of road rollers relies solely on the weight of the drum to compact material. The absence of vibration mechanisms makes static road rollers easy to operate and maintain. Static rollers are suitable for most material apart from cohesive soils. The need for several passes to attain the required degree of compaction makes using static rollers expensive and time consuming.

Vibratory road rollers

Vibratory road rollers are most ideal for compacting granular materials. The drum on these rollers are fitted with eccentric weights that are triggered electronically to generate vibrations. The vibrations, coupled with the weight of the drum effects compaction to the required degree. Vibratory road rollers require less passes to attain required compaction. While passing over the material, the vibrations eliminate more air from the particles resulting in a denser material.

Despite the suitability and benefits, overusing vibratory road rollers could damage the material under compaction. Additionally, the vibrations generated by the roller could be destructive to the surrounding structures on site. The cost of maintaining vibratory rollers is higher since the eccentric weights and vibration mechanism need regular checking.

An expert is needed to ensure the roller doesn’t damage the material under compaction or the surrounding structures; this raises the cost of operation.

Components and Controls or Road Rollers

As a construction equipment specialist, the efficient working of a road roller relies on various components that have vital roles in its operation. Let’s delve into the essential parts and features of road rollers, rearranged for clarity and readability:

Drum

The drum, a critical component, serves as the compaction interface between the roller and the material being compacted. Made of heavy metal, the cylindrical drum enables effective compaction. By exerting weight, the drum forces material particles closer together, eliminating air voids. Vibratory rollers employ drums with eccentric weights that generate vibrations. Different drum types are available, each suited for specific applications:

Smooth drum: With a smooth surface, these drums are ideal for compacting granular soils. They apply uniform pressure, making them suitable for cohesive materials as well.
Padfoot drums: These drums have cylindrical or rectangular shapes and feature protruding pad or feet-like structures. The pads create concentrated pressure points on the surface, making padfoot drums effective for compacting cohesive soils, clay, or other cohesive materials.
Pneumatic drums: Hollow and made of rubber, pneumatic drums can be filled with air or water. They are used for compacting asphalt, providing a smooth and uniform surface finish. The rubber material prevents surface damage and offers improved traction.
