The angle of repose or the critical angle of repose, of a granular material is the steepest angle relative to the horizontal plane which a material can be piled without slumping or the surface material sliding.
The angle of repose is a direct measure of the aptness of material to flow: the lower the angle, the more the material flows (think about it: water has an angle of repose of 0 0 0: it flows so well!), while for higher angles we witness materials that oppose to flowing. The granulometry of a material is one of the core elements that affect the ...

If so, a quick way to guesstimate a friction angle is to pile the crushed stone on top of eachother and then measure the angle of repose. 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 angle of repose of sediments was theoretically [75, 76] and experimentally [77] examined. Yang et al. [78] investigated the angle of repose of non-uniform sediments to study bed slopes and sediment transportation. The angle of repose of the sediments was tested by using air and water in a method similar to the revolving cylinder method.

Question: Find the size of a conical stockpile resulting from the excavation of 1,000 BCY (765 BCM) of gravel. Swell is 14% and angle of repose is 35degrees. Find the size of a conical stockpile resulting from the excavation of 1,000 BCY (765 BCM) of gravel. Swell is 14% and angle of repose is 35degrees. Here's the best way to solve it.
Stockpile Height vs Diameter Repose Angle - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This graph shows the relationship between stockpile height, diameter, and angle of repose. Stockpile height increases exponentially as diameter increases for a given angle of repose. Steeper angles of repose allow taller stockpiles for a given diameter.
