In simulation of railway ballast behaviour using Discrete Element Method (DEM), it seems to be necessary to take into account the crushing and the abrasion of grains. Nowadays, two approaches have been used in discrete modelling. The first approach represents each grain as an assembly of smaller units with cohesive contacts between them [1, 2].

Jan 01, 2003 The Aggregate Crushing Value (ACV) test is another constrained comminution process, and so should give a good representative measure of degradation beneath the track. The ACV test involves crushing an aggregate of 10mm-14mm ballast particles in a 154mm diameter and 134mm deep steel mould.

• Ballast quality and ability to resist crushing forces (ballast degradation is the number 1 cause of ballast fouling) – Some railroads use different track modulus (u) values in design. For example, Spring u may be used for rail bending and ballast depth, but Winter u used for rail seat forces. Other railroads may use a single u

Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily. Ballast is produced from natural deposits of granite, trap rock, quartzite, dolomite or

A hypo-plastic approach for evaluating railway ballast

Sep 14, 2017 Repetitive or cyclic rail loading deteriorates the engineering properties of the railway ballast by particle crushing and rearrangement. Most of the classical elasto-plastic models are unable to predict such ballast degradation despite successfully predicting the overall load–deformation behavior during cyclic densification. In this context, the present study delivers a novel hypo-plastic

May 01, 2006 Ballast is transported from quarries (sometimes railroad-owned, mostly private) in special hopper cars whose bottom doors facilitate its precise dumping on either side of the rails. At the work site, ballast cars are moved along slowly by a locomotive, with track-crew members on the ground regulating the flow of rock by opening and closing the

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing

Broken stone is a widely used ballast in railways. It is obtained by crushing hard stones like granite, hard trap, quartzite etc. In lieu of broken stones, limestone and sandstone can also be used. It is suitable for high-speed railway tracks. The broken stone selected as ballast should be hard, tough and non-porous.
