What is the typical speed range for a multitiered pneumatic vibratory roller?

• A. 2-4 mph
• B. 6-8 mph
• C. 1-2 mph
• D. 5-15 mph

Answer: (D)

When you’re using a multitiered pneumatic vibratory roller, the goal is to combine vibration and the kneading action of the tire contact to densify material efficiently over a large area. The tire rollers provide continuous contact and smooth the surface, while vibration helps break up soil structure and push particles into a denser arrangement. That combination works best at moderate to higher speeds compared with other rollers, so you can cover more ground without losing the benefits of the kneading and vibration. A typical operating speed around 5 to 15 mph strikes that balance: it’s fast enough to be productive on large projects, yet slow enough that the roller spends enough time under load for the vibration and kneading action to compact effectively. Going slower yields diminishing returns in a practical sense, since you’re not increasing density much per pass, and going much faster reduces the time under load and can compromise uniform density and surface finish. Actual speed is adjusted for material type, lift thickness, and temperature, but 5–15 mph is the common range for this equipment.
