How does a road roller work?

Road rollers use the weight of the vehicle to compress the surface being rolled (static) or use mechanical advantage (vibrating). Initial compaction of the substrate on a road project is done using a padfoot drum roller, which achieves higher compaction density due to the pads having less surface area.

What is a road roller called?

4. Sheepsfoot. Sheepsfoot rollers, otherwise known as padfoot or tamping rollers, are rollers with many rectangular-shaped lugs, or “feet.” They’re great for compacting soil and silty clay in road construction work.

The textured bumps on the roller assist with compacting silty clays, allowing the padfoot roller to move over the surface without lifting sticky mud or clay off on to the roller drum. These single drum units use a combination of weight, vibration and shearing motions to compact heavy soils.
