Sophisticated roller compaction technologies and roller-integrated compaction control

In this paper compaction technologies are considered in form of rollers equipped with different kinds of exciters. Compaction of soil, fill material, etc. normally takes place by vibratory rollers, whereby the vibration of the drum is caused by a rotating mass excenter. In the last years dynamic rollers with different types of excitation where developed. The paper is focused on the oscillatory roller, the VARIO roller, and the automatically controlled VARIO CONTROL roller. Furthermore, the paper contains roller-integrated compaction control methods in order to check continuously the compaction success during compaction with different dynamic roller types. Finally, the application of new compaction technologies and case histories, where roller-integrated continuous compaction controls (CCC) were used, are reported.
