Continuous Compaction Control (CCC) systems are used with dynamic rollers. The basic principle is the assessment of the soil stiffness or compaction respectively based on an evaluation of the motion behaviour of the dynamically excited roller drum. CCC has become the state of the art method for an assessment of the compaction success over the past decades. Since it is a continuous roller- and work-integrated method, it is much more efficient compared to spot-like testing methods.
However, the application of CCC systems was limited to vibratory rollers. Therefore, the German roller manufacturer HAMM AG and the Vienna University of Technology launched a research project to investigate the motion behaviour of oscillatory rollers and the aim of developing the first functional CCC system for oscillating rollers.
Large-scale in situ tests were performed as well as theoretical investigations, which resulted in a CCC system for oscillating rollers. The study covers the basic principles of CCC systems, a description of the novel CCC value for oscillating rollers and a validation of the CCC system for oscillating rollers on the example of three roller types. Finally, recommendations for an ideal application of the new CCC system are provided.
