What Is a Roller?
A roller is a ride-on machine primarily employed in road construction to compress the multiple layers of materials essential for road building. In addition to road construction, rollers find utility in other compaction tasks, such as trash compaction or preparing surfaces for parks and fields. These machines, characterized by their large size and ride-on design, are distinct from handheld compaction equipment.
For projects necessitating extensive ground compaction, rollers are typically the preferred construction equipment. They are indispensable except in cases of restricted access, where their size precludes their use on the construction site, or when the area requiring compaction does not justify the expense of renting a roller. Below, we delineate the various types of rollers available for hire.
What are the different types of rollers?
Various types of rollers serve specific functions in construction projects. The primary categories include smooth drum and padfoot rollers. Smooth drum rollers feature circular drums for compacting granular materials, while padfoot rollers employ flat, wide spikes to expel air from soil and clay, enhancing compaction. Additional roller variations include:
- Single and Tandem Drum Rollers: Single drum rollers feature one drum at the machine’s front, complemented by standard wheels at the rear. Tandem drum rollers, in contrast, incorporate two drums, one at the front and one at the rear.
- 4-Wheel Padfoot Roller: Primarily utilized for landfill compaction, these rollers substitute smaller wheel-sized rollers for tires, facilitating traversal over debris piles for compaction.
- Pneumatic-Tyred Roller: Also referred to as rubber tyre rollers, they function as finishing and sealing rollers, proficient in smoothing uneven surfaces to achieve desired levels of compactness.
What Is a Compactor?
A compactor, commonly referred to as a plate compacting machine, is typically operated by pedestrians. These machines, known as plate compactors, are compact and designed for pedestrian use, primarily to compact driveways and walkways.
They serve as smaller, walk-behind compacting machines suitable for compacting areas where larger ride-on rollers cannot access, making them ideal for jobs with tight access constraints.
Despite being overlooked by some road construction companies as unnecessary equipment, compactors prove to be highly versatile and beneficial on construction sites.
During road resurfacing or upgrading projects, there are often hard-to-reach areas or small sections away from the main construction zone where a standard roller cannot be used due to size limitations or accessibility issues. In such scenarios, project managers typically seek out a plate compactor to efficiently address these specific compacting needs.
What are the different types of compactors?
A diverse selection of compactors is available for rental, though their range is not as extensive as that of rollers. Nevertheless, they are proficient in executing comparable compacting tasks, spanning from compacting light soil and rocks to granular materials. The primary types of compactors include:
- Rammer: These high-powered compactors are utilized for compacting small areas and excel in tight access construction projects. They serve as effective alternatives to rollers in such scenarios.
- Vibrating plate: Vibrating plate compactors are well-suited for larger walk-behind compacting areas, such as driveways and footpaths. They offer enhanced efficiency in these settings.
