Friction angle of crushed rock - Geotechnical engineering ...

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.
