Choosing the right size vibrating roller depends primarily on the required depth of compaction, also known as the lift thickness.
Determining the correct size of a vibrating roller is crucial for effective compaction on your project. The necessary size is directly related to the depth of the material layer you need to compact. Vibrating rollers utilize centrifugal force in addition to their static weight, allowing them to achieve compaction at greater depths compared to non-vibrating or pneumatic rollers.
Based on typical guidelines derived from compaction requirements and roller capabilities:
- For compacting lifts up to 150mm (approximately 6 inches), you generally need a vibrating roller that weighs up to 7 tonnes.
- If you are working with lifts up to 300mm (approximately 12 inches), a heavier vibrating roller, typically weighing up to 15 tonnes, is recommended.
- For projects requiring deeper compaction than 300mm, you will need a vibrating roller weighing over 15 tonnes.
Here's a quick reference table summarizing these guidelines:
| Required Compaction Depth (Lift Thickness) | Recommended Vibrating Roller Size |
|---|---|
| Up to 150mm | Up to 7 tonnes |
| Up to 300mm | Up to 15 tonnes |
| Deeper than 300mm | Over 15 tonnes |
Remember to consider the specific material being compacted and the desired density, as these factors can also influence the optimal roller size and the number of passes required. However, the lift thickness is a primary determinant for selecting the appropriate roller weight class.
