Cat Pneumatic Rollers work effectively on a wide range of applications. Models with oscillating wheels are used on sub-grade soil, granular material or cold mix to create additional density and find weak areas so they can be repaired before paving. Cat Pneumatic Rollers are also used on hot mix asphalt in the initial breakdown and intermediate phases to increase density and to seal the surface of the mat. Lightweight models create a tight bond when applied to chip and seal surfaces.It's easy to tailor the ground contact pressure to the job. Cat models have easy-to-fill ballast tanks, modular steel ballast configurations and various tire options.

Get it dense and keep it smooth. Cat Tandem Vibratory Rollers do that and more. Caterpillar offers a vibratory system for every application. Most models have high frequency combined with low amplitude that match high paving speed on thin lifts as well as low frequency with high amplitude that match low paving speed on thick lifts of stiff material. As stand-alone units or as complements to high production tandem rollers, Cat Utility Rollers set the standards for versatility and reliability. A wide range of drum widths lets you precisely match the machine to the job requirements—whether it's a narrow shoulder, a patching project, a parking lot or a bicycle path. Vibratory systems are characterized by high frequency for fast working speed and high compaction energy for getting density in the fewest passes.

Smooth drum compactors produce consistently reliable results when compacting semi-cohesive and granular materials. With operating weights up to almost 19 metric tons, there is a Cat Soil Compactor sized to meet the most demanding production and density requirements.Padfoot drum compactors produce consistently reliable results when compacting semi-cohesive and cohesive materials. Pads are tapered and penetrate deeply into the soil to build strength from the bottom up. Small pad face area concentrates force to deliver the highest compaction energy so production goals are met with fewer units and less fuel consumed.All dual-amplitude models feature an exclusive Cat eccentric weight design that assures positive amplitude selection while preventing contamination of the weight shaft bearing lubrication.
