Rolling dynamic compaction
This project focuses on the concept of rolling dynamic compaction, whereby a truck carries a four-sided roller that rotates and compacts a soil sample.
A 1:13 scale model of a four-sided roller has been produced within the laboratory in order to simulate the roller’s behaviour and ability to effectively compact soil, the findings of which can then be applied to a full-scale scenario.
To do this, the following methodologies will be employed; Tekscan pressure sensors and Earth Pressure Cells will be embedded within a mass of soil to measure changes in pressure as the model compactor passes over the soil and a 3-dimensional scan of the soil profile will be taken to visualise changes within the soil profile. In this study, we hope to obtain a definitive link between roller and soil properties, such as speed, weight and moisture content.
