The roller is a steel cylinder that oscillates and or vibrates to eliminate the gaps between the small materials in the soil, aggregate, or asphalt. Some rollers work on concrete. The operating weight of the machine provides compaction as well as the roller attached to it. Additional ballast can be added, usually in the form of water or sand.

For sand or polymeric sand to settle in the joints between pavers, the vibration of the compactor is critical. The vibration is what makes it look like the cracks are full, even though below the bridge they are empty/hollow. Furthermore, vibrations compact the sand grains with fine dust between them, which further reinforces their joining.

The vibrations allow individual soil particles to move in any unrestrained direction, hence filling the gaps and making the soil more dense and compact. These rollers are particularly useful for compacting granular soils like sand and silt or soils having greater percentages of these two types of materials.
