Friction angle of crushed rock Geotechnical engineering

Oct 02, 2007Friction angle of crushed rock. 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
