Continuous Compaction Control (CCC) with Oscillating Rollers

Soil is loaded horizontally by the drum motion and vertically by the dead load of the drum and roller. While CCC systems have become the state of the art in compaction control for vibratory rollers during the last decades, the lack of a CCC system for oscillating rollers has been a major disadvantage of these rollers.

Cat | Two Machines in One Compactor | Caterpillar

With some other rollers, the vibratory and oscillating drums have different variable frequencies—yet only a single frequency gauge. That means the amplitude changes only as the operator adjusts frequency. The result: The roller never properly matches the job’s demands. In addition, operators find this system difficult to understand and therefore seldom make the proper adjustments. (See the sidebar for an …
