Abstract: The dynamic response of the vibrant roll in resonance regime highlights the rheologic influence of land. Thus, for the land linear viscoelastic modelled Voigt-Kelvin or Maxwell the dynamic response in resonance may characterize the rheological and dynamic nature of the compactor roller-land interaction. This paper presents the results of the dynamic modelling highlighting the resonance regime and the technological dynamic regime in post-resonance. Thus, there are presented the results obtained for real cases, with "in situ" experiments based on which certain correlations of the response curve with the degree of compaction of the land.

Key words: dynamic compaction, soil, rheology
