 Depth of ballastis measured under the rail seat and does not include the capping layer or sub ballast where used.  On superelevated track, the depth of ballast is measured under the low rail.  Through turnouts the minimum ballast depth under turnout bearers may be maintained by lowering the formation level as required.

Simulation of particle flows and breakage in crushers
Apr 01, 2015The primary fragment diameter is chosen randomly in a range from S min to R parent where S min is the smallest primary fragment radius allowed and R parent is radius of the parent particle that is fracturing. In general S min is chosen to be dependent on the collision energy or the fracture force with it decreasing with increasing intensity of the breakage event.
