SHAPE AND SURFACE ROUGHNESS EFFECTS ON MAXIMUM AND MINIMUM VOID RATIOS OF SAND

Gary M. Norris

Open publisher page 2 citations

Abstract

Recent work by Youd describes a program undertaken to carefully test and characterize the influence of particle size, shape and gradation on maximum and minimum void ratios of sand. A significant improvement upon previous work is Youd's quantitative assessment of particle shape with parameter, roundness, as opposed to purely qualitative assessment and description-well-rounded, rounded, subrounded, subangular, angular. Youd interpolates test data to provide generalized curves of maximum void ratio versus uniformity coefficient for different values of roundness; particle size was found not to be a factor. Similar curves are presented for minimum void ratio. The current work seeks to compare results for very uniform sands with the Youd curves and evaluate the potential error for a factor heretofore neglected, surface roughness. (Author)
