ABSTRACT
Continuous Compaction Control (CCC) is a process that uses the measurement of the drum’s compactor vibrations (acceleration) to estimate the stiffness of the soil during compaction and then have a real time assessment of the soil compaction. This paper presents the development of a reduce-scale physical model of a vibratory roller compactor, which will be used to simulate continuous compaction control in a centrifuge. The model was conceived by scaling the drum’s weight, diameter and the centrifugal force generated by a commercial vibratory roller compactor to be used in centrifuge at 10 g. Soil deformation analysis was also done during the test, by using particle image velocimetry (PIV) method, in order to analyse the soils’behaviour. Results show that the scale model reproduces the effects of vibratory roller compactors on soils and also how the force increases and displacements decrease as the soil is compacted in time.
