Railway Ballast Quality Specifications as RDSO GE-01 (2016) Physical Qualities of Track Ballast: Ballast should be hard durable, free from the weathered portion of parent rock, organic impurities, and inorganic residues.
Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
Railway vehicles and components. Railway basics. Side cuts. An earthwork on the slope. If tracks need to run along the side of a mountain a side cut needs to be made on the side of the mountain. It allows horizontal track geometry and overall the first line layout. The side cut is, so to speak, a half cutting in combination with half an embankment.
Brick Ballast. Selected Earth. 1. Broken Stone. Broken stone is one of the best materials for railway ballst to be used on the railway tracks. Almost all the important railway tracks are provided with broken stone. The stone to be used as railway ballast should be hard, tough nonporous and should not decompose when exposed to air and light.

NOTE Reused railway ballast: railway ballast resulting of previously used railway ballast on site and without putting it on the market is not covered by this European Standard. It also specifies that a quality control system is in place for use in factory production control and it provides for the evaluation of conformity of the products to this European Standard.
Functions of track ballast. In fact, the track ballast serves a number of purposes. First of all, it makes sure that tracks stay in place when super-heavy trains roll by on them. It also plays an instrumental role in keeping any vegetation in check that might grow around the tracks (and make the ground beneath the tracks …
In addition to the classical design of track grid floating in ballast, other non-conventional designs have been developed with varying degrees of success. The railway permanent way has an average useful life of between 30 and 60 years.
01-01-2001· Railway track formations generally consist essentially of a layer of coarse aggregate, or ballast, in which the sleepers are embedded (see Fig. 12.1). The ballast may rest directly on the subgrade or, depending on the bearing capacity, on a layer of blanketing sand. The layer of ballast is intended to provide a free draining base which is stable enough to maintain the track aUgnment with …
04-06-2020· Railway ballast or track ballast refers to crushed stones placed under the railway track. It forms the trackbed for sleepers to lay on. Although some tracks are ballastless, the ballasted track remains a dominant infrastructure of the most railroad tracks. Why is that? Ballast in railway may seem inconspicuous, but its function plays a key role.
What is track ballast. To start with, the stones that you see lying close to the railway tracks are collectively called track ballast. It basically forms the trackbed on which the rail sleepers are kept. Track ballast is packed between the sleepers, in the areas below, and on the sides of railway tracks.

Rail track ballast forms the bed on which sleepers are laid and is traditionally packed between, below and around the ties. The idea is that it is used to help drain water away, while also minimising the vegetation that could potentially impact the railway structure.
Rail track ballast serves as a bed for rail tracks and provides drainage and strength for heavy loads carried by trains. Ballast is the description for the aggregate beneath the rail track. The track ballast forms the track bed that suports the rail track load and provides water drainage.
aspects of railway ballast, track structure, train/track interaction, and track settlement.

Types of Ballast Used in Railway Track ...
Track ballast should never be laid down less than 150 mm (5.9 inches) thick; and high-speed railway lines may require ballast up to 1⁄2 metre (19.7 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions overloading the soil causes the track to sink, usually unevenly.
05-04-2021· As evidenced in the UK and worldwide, railway track buckling can still occur even if the railway tracks are fully supported and the ballast layer seems to be in good condition by visual inspection. In fact, degraded ballast particles and the accumulation of ballast breakdown or outside contamination, such as subgrade intrusion or coal dust, often may not be seen visually [5], [6] .
Ballast Rail Track. Ballast refers to the gravel or crushed rock paved on the road or railway subgrade, it is mainly used in railway subgrade. Ballast is one of the main components in the railway transportation system, used to support the railway sleeper and rail track.
