Ballast Trains Magazine. Down below the trains, below the rails, the tie plates, and the ties, is a lowly yet vital component of railroading track ballast. While ballast may not be at the top of anyone's list of rail topics, it's literally part of the foundation of railroads, and it can comprise more than 80% of the weight of the track structure.

• Road-layer works material includes the base and sub-base materials that provide the supporting, interlocking structure in road design. The different categories of graded material cater for varying load designs. • Speciality aggregate include railway ballast, gabion and other larger sized crushed
the ballast may be rejected following petrographic analysis or durability testing, even though the rock complies with other sections of the specification. 6.2 Bulk Density When determined in accordance with AS 1141.4 the compacted bulk density of ballast material shall not be less than 1200 kg/m3. 6.3 Particle Density
2. Ballast material Ballast is the main structural part of railroad where the sleepers (or ties in US) are laid. Its main function is to transfer the loads coming from the super structure to the subgrade without failure and providing good drainage. Different types of materials used for ballast construction
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 ...

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.
The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic metre) (see table below)

The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3).
The specific gravity and bulk density of the ballast are two properties that play pivotal roles in rail track safety. Bulk density is a function of the particle specific gravity and the void ratio. Two methods can be employed to increase the bulk density: the use of denser particles, and a broader gradation.
Steel Ballast for General Purpose Applications: Clean, screened and oil-free steel materials to meet your most stringent weight standards.Our regular steel ballast will have a density of 260-265#/cubic ft density. We generally suggest a reclaimed S110, G70 or G80 media for general ballast applications due to availability of these sizes, packability, and price.
• Mean values for a large number of different materials are given in EN 1991-1-1 Annex A. • For materials not in Annex A either: - the characteristic value of density needs to be determined in the National Annex, - a reliable direct assessment is carried out (eventually according to EN 1990 Annex D).
