The specific surface of coarse particles like sand and fine grained soils like silt and clay plays an important role in geotechnical engineering field.
In this context, are there any anlytical methods to identify the combination between specific surface of coarse particles with fines grained soils?.
Also this ppt can be helpful to further investigate. http://www.karlin.mff.cuni.cz/~prusv/ncmm/workshops/wog/download/robinson/interfacialFrictionBetweenSoilsAndSolidSurfaces.ppt
