Modeling the Dynamic Interaction between a Vibratory-Compactor and Ground

Abstract

There have been proposed various models for the structural analysis of vibratory compactors, with different degres of freedom, in order to know the dynamic response of the road compaction process. In the same way, many rheological models for the materials of the soils have been developed so as to represent the behavior of the ground, usually based on characteristic parameters which describe the compaction process of the soil. Based on experimental measurements, this paper aims to establish the connection between the actions of the vibratoy-compactor and the effect of those actions in the ground during the compaction process and to predict the effects of a conducted action under known conditions. Better understanding the compaction process will lead to better qualities in embankments, and, consequently, pavement deterioration will be delayed, particularly rutting, and structural parameters of roads will deteriorate more slowly.
