Field testing of automatic frequency control for intelligent compaction of embankments

Wersäll, C. and Persson, A., (2021) “Field testing of automatic frequency control for intelligent compaction of embankments”; International Conference on Transportation Geotechnics, Digital event 24-27 May 2021.

A newly developed intelligent compaction method, automatic frequency control (AFC), has been tested in full-scale field tests. The technique utilizes measurements on the drum to determine the resonant frequency of the dynamic roller-soil system and provides continuous feedback to the roller for automatic adjustment of the frequency.
