Smooth drum rollers rely on static pressure and vibration for granular soils (sand, gravel) and asphalt. Padfoot rollers have tapered lugs on the drum that penetrate the soil, making them essential for compacting cohesive soils like clay and silt.

Centrifugal force measures the compaction energy generated by the vibrating drum. A higher centrifugal force allows the machine to achieve deeper compaction lifts, meaning you can compact thicker layers of soil in fewer passes.

Static linear load is the weight of the roller divided by the width of the drum. This spec indicates the “squeezing” force the roller applies when not vibrating, which is critical for finishing passes and asphalt work.

Many smooth drum rollers listed in our specs can accept a ‘padfoot shell kit,’ which clamps over the smooth drum to convert it for use on cohesive soil. Check the model details to see if this versatility is available.
