Roller Compaction - Impact of Dynamic Drums in Comparison

摘要

In the presented study two different types of excitation for the dynamic roller drum are compared in terms of their impact on soil, the vibratory drum and the oscillatory drum. Their differences in functioning, mode of operation and loading the soil are outlined. First results of large-scale in-situ tests are presented in which the vertical earth pressure, deformations and tri-axial accelerations have been measured. Moreover, the influence of the type of excitation on ambient vibrations is discussed.
