Which rolling speed is appropriate for pneumatic tired rollers?

The choice of a rolling speed of 5 mph for pneumatic tired rollers is appropriate due to several factors related to the effective compaction of materials. Pneumatic tired rollers work by utilizing rubber tires to apply pressure to the surface being compacted. This pressure is essential in achieving the desired density and smoothness.

At 5 mph, the roller is able to adequately perform the necessary kneading action that is beneficial for compaction, particularly of asphalt and granular materials. This speed allows for enough time for the tires to effectively compress the material without causing displacement or damage. Additionally, rolling at this speed minimizes the risk of surface tearing, which can occur at higher speeds, thus ensuring a uniform and stable surface.

In contrast, rolling too slowly may not adequately compress the material, while speeds beyond 5 mph might reduce the efficiency of compaction and lead to poor surface quality. Balancing speed and compaction effectiveness is crucial in roadway construction, making this choice optimal for the application of pneumatic tired rollers.
