Most construction sites need to have leveled ground to do further construction work. The soil must be compressed to prevent underground air pockets that could disrupt the process. Therefore, contractors compact and smooth ground using special equipment called rollers. Road rollers are often used for constructing roads or creating compact foundations for large areas or diverse areas like landfills or agricultural projects. The primary application of different types of rollers is to crush, knead, and vibrate loose materials by directly applying high pressure. Here enlisted are different types of road rollers a constructor can rent for a cost-effective construction project.
- Grid Rollers
Grid rollers have a network of steel bars that creates a grid-like pattern with square-shaped holes. These rollers are commonly ballasted with concrete blocks or steel attachments. Grid road rollers are usually towed or pulled behind a tractor or heavy machine.
With grid design on the cylinder drum producing a high contact pressure while leading on compaction work, these road rollers are suitable to work on well-graded, coarse soils and weathered roads. Moreover, grid rollers are used chiefly for sub-grade, sub-base road construction projects.
- Smooth Wheeled Rollers
Smooth wheeled rollers have two steel drums in the back and a single large steel drum in front. The gross weight of these road rollers ranges from 8 tonnes to 10 tonnes. Among the types of rollers in this category is the Tandem roller, which weighs 6-8 tonnes.
The performance of such rollers depends on their load per cm width and rolls diameter. Smooth wheeled rollers are suitable for compaction when the material doesn’t need tremendous pressure. In addition, construction contractors also rent these rollers to finish the upper layers.
- Sheepsfoot Rollers
A static and vibration type machine, the Sheepsfoot roller is mainly used for compacting soil mixed with all fine-grained clay and sand gravel. Modern models are equipped with metal drums with luggage fixing and can pressurize up to 14 kg/sq.cm.
The weight of Sheepsfoot drums can be increased by ballasting them with water or damp sand or mounting steel sections onto them. These road rollers are primarily used in road and rail projects.
- Padfoot or Tamping Rollers
Padfoot or Tamping rollers are similar to Sheepsfoot rollers, but the former ones have lugs of larger areas than the latter ones. The static weight of status Padfoot rollers weighs 15 to 40 tonnes, and their static linear drum loads lie between 30 and 80 kg/cm.
Construction contractors can achieve more compaction and density uniformity with tamping rollers than with Sheepsfoot rollers. These road rollers operate at high speed, break large lumps, and compact clay materials from 30 to 40 cm thick.
Conclusion
Compacting the loosely bound foundation materials using the rolling process is necessary to prevent them from coming loose and maximize the construction output. Choosing the right road roller fitting specific project criteria from many available options is critical to completing a construction project successfully. Moreover, many constructors decide to rent different types of rollers by figuring out the right roller rental depending on the project’s length, soil type, and work involved.
