Kurzfassung englisch:
The paper provides a state of the art overview of compaction technologies and moreover integrated vibration based measurement systems used on dynamic rollers and heavy tamping technique to continuously measure soil properties during and after earthwork compaction. Roller measurement values have evolved towards the estimation of more mechanistic soil parameters, e.g. stiffness modules. Independent assessment of these measurement values has proven their efficancy. Heavy tamping is a deep dynamic compaction technique and has been increasingly used since beginning of the Seventies of the last century. The authors report on in situ measurements and theoretical investigations referring to the delay of free soil vibrations caused by the falling weight after each impact. The Rapid Impact Compactor is an innovative dynamic compaction device based on the piling hammer technology used to increase the bearing capacity of soils trhough controlled impacts. This ground improvement technique allied to dynamic compaction has been recently introduced in Central Europe. An integrated measurement system is currently under development.
