Angle of Repose for Chrused rock - Foundation

2006-6-12 · For "Gravel,dry, 1 inch and under" the angle of repose is given as 36 degrees, 52 minutes. (This false precision comes from back-figuring the given slope ratio of "1 on 1 1/3"). See page 8. "Limestone, fragments, dry, 1 inch and under" angle of repose = 45 degrees. Must be very dependent on the material that the crusher run is made from.
