Measurements are presented for the angle of repose (alpha(r)) and the maximum angle of stability (alpha(m)) of a slope of poured granular material. Results using monosized grains with three materials of differing shape are presented. This is followed by results with binary mixtures. The results demonstrate a strong relationship between the slope angles and particle shape and that particle size distribution affects the slope angle and avalanching mode, especially as the grains become less spherical.
