With increasingly limited space available for infrastructure development, engineers are forced to infill in less desirable areas such as landfill sites. Landfill is prone to decomposition and is highly heterogenous, resulting in significant differential settlements when subjected to development loads. Ground improvement via impact rolling is a practical tool geotechnical engineers can employ to manage these difficult ground conditions. Impact rolling densifies the near surface material and collapses voids, reducing potential differential movements. This method is commonly used for shallow embankment infrastructure such as roads and runways. Predicting the settlement induced from impact rolling can be challenging due to high variability in landfill materials, limited empirical relationships, and a lack of a standardised design methodology.
