    2018-5-1 · The angle of repose of sediments was theoretically [75,76] and experimentally examined. Yang et al. investigated the angle of repose of non-uniform sediments to study bed slopes and sediment transportation. The angle of repose of the sediments was tested by using air and water in a method similar to the revolving cylinder method.

    2007-10-2 · The angle of internal friction of a crushed stone will be directly influenced by type of rock and grain size. Forty-one (41) seems to me possible, but dangerous. I would use a safe 36 degrees unless a direct shear test is performed on a sample. There's at-rest earth pressure and active earth pressure.
