Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.
Track ballast is the rock under the train tracks. This ballast is there to prevent the track from moving when a very heavy train runs over it. It also protects the track from anything that can prevent the safe operation of the trains. Most of the time, track ballast is made out of crushed rock. But, this sometimes needs to be replaced.

The railroad track structure spreads the load to the ballast below. Because ballast material is angular crushed rock, the crushed ballast locks together as a matrix, which transfers these large loads from track structure to the sub ballast below. Railroad tracks move as the train passes over the track. A good ballast allows (but restricts) this

Vulcan produces ballast and other track materials for shipment to customers from coast to coast, and has a dedicated Ballast Sales Team that can help you with your ballast needs from any of our facilities.
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).
We serve 18 ballast stone quarries on our 20,000-mile network. Typical ballast stone types range from trap rock to granite. Most locations are capable of unit train shipments, and single-car and block shipments are also available. CSX can provide aggregate hopper cars for your convenience or you can provide your own ballast hoppers.
The ballast distributes the load of the ties (which in turn bear the load of the train on the track, held by clips) across the foundation, allows for ground movement, thermal expansion and weight

Aug 20, 1996· There are a number of high risk silica exposure jobs in track repair and track maintenance jobs with railroads such as Norfolk Southern, CSX and the other major U.S. railroads. Many of these workers operate heavy machinery that manipulate, groom and otherwise disturb railroad track rock (called "ballast rock"), often creating clouds of silica dust.
This layer of ballast is made of small, coarse rocks of various shapes and materials. It is important that these rocks be irregularly shaped and not uniform, as they will pile up and hold stronger. This ballast will fill in all the gaps between and underneath the sleepers and rails, providing a strong base for the track

May 17, 2007· Primarily, ballast needs to be made from a rough rock that drains water easily, "locks" together well so it doesn't move around and let a train derail, and it has to be durable if it's on a line with much traffic so it doesn't break down as quickly under the weight of passing trains. That's why pumice isn't very good for ballast, it crushes too
Dear Randy, Unfortunately, I just figured out that the supplier will also effect the equation. My example above used a local supplier "Chuck's Ballast", but I know that Heki, WS, amd Arizona Rock and Mineral all offer similarly-tagged "fine" material which is a markedly different agregate size, and thus may not cover the same ammount of ground.
Railroad Ballast is a recycled product commonly made up of crushed limestone or other rock. It is primarily used during the construction and maintenance of railroads, holding the wooden cross ties in place and in turn, holding the rails in place.

Aug 08, 2016· Four types of geosynthetics and a shockmat were installed below the ballast layer in selected sections of track constructed on three different subgrades (soft alluvial clay, hard rock, and concrete bridge), and the performance of the instrumented track was monitored for five years under in-service conditions including tamping operations.
undesirable level due to subgrade settlement and ballast degradation, ballast is added to raise the track. This typically does not solve the problem and after some time in service, more ballast is required. This cyclic process of ballast dumping, surfacing, and subsequent track settlement has been the status quo in the U.S. since the 19th century.
