Roller Types
The right roller depends on the material being compacted:
- Single-drum vibratory roller — granular soils, gravel and road sub-base.
- Padfoot (sheepsfoot) roller — clay and cohesive soils in embankments and dams.
- Double-drum (tandem) roller — asphalt surfacing and finishing.
- Pneumatic tyre roller — sealing asphalt and chip-seal surfaces.
- Plate compactor or rammer — trenches, footpaths and small areas next to structures.
