Friction angle of crushed rock

 · A true crushed stone slopes would fail by sliding parallel to the slope. When the slope angle exceeds the angle of internal friction, the stone grains should slide down the slope. The steepest slope that the crushed stone slope can attain, therefore, can be said to equal the internal friction angle of the stone.
