Abstract
An iterative approach combining boundary element method (BEM) and roller-drum geometry has been developed to estimate the drum-soil contact width. The approach shows good agreement with Hertz theory predictions on half space of known elastic properties. Contact width dependency to layer characteristics has also been examined and indicates the influence of soft subgrade on the variation of contact width. The developed method allows an understanding of contact width variation with roller geometry as well as layered soil characteristics and can be used in sensitivity studies.
