Angle of repose - Wikipedia

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or diprelative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of repose; smooth, rounded sand grains cannot be piled as steeply as can rough, interlocking sands. The angle of repose can also be affected by additions of solv

Crushed gravel, on the other hand, is produced by the natural processes of weathering and erosion, and typically has a more rounded shape verses the angular surfaces of stone. This material comes in sizes generally ranging from less than a half inch up to 20” in diameter. The smooth surface of the stones makes it a good choice for driveways, walkways and more decorative landscape use. Color ...
