Historically, the ballast a railroad used was what was available on line, hence limestone in the south, ganite in the west, cinders or dirt anywhere, etc, as you note. As demands for a better track structure developed, many things changed. Ties got bigger, rail got heavier and the need for a good solid base to build it on got more critical.

The ballast isn't just a uniform colour, but has a subtle blend of dark and light stones because ballast often has crystalline or darker impurities. The traditional method of fixing ballast is to apply a 50:50 ratio of PVA and water, with a drop of washing up liquid. When applied, the diluted glue trickles through the ballast and dries to ...

Rail Ballast (35mm-50mm) Rail aggregate needs to be irregularly shaped to work effectively and have sharp edges that are able to interlock together to create a strong foundation for the railway track. Our top quality rail ballast is available in bulk bags and loose tipped, a CE performance certificate can be provided on request.

Ballast also acts as a support base for the railroad track structure giving it strength and rigidity but also allowing for flexibility when trains pass over. Limestone or quartz is often most used as ballasting because it is a hard stone that will lock together providing for extra strength.

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 ...

Aggregates in Railroad Ballast. Railroad ballast is one of the most demanding applications for aggregate, or crushed stone. Shoreline delivers both expertise and aggregates. Over 200,000 miles of railroad track cover the United States. Today's trains can exert a force of 100 psi (pounds per square inch) when passing over track – and those ...

railway ballast The function of ballast in railway track. Ballast is a common trackbed structure in the railway transport system, which is used to support track sleepers. A layer of crushed stones will be laid on the roadbed before the tracks are laid, which will then be compacted. Then sleepers and tracks will be laid.

Walking Ballast is also known as ballast stone, railroad ballast, mainline ballast, shortline ballast, yard ballast, AREMA ballast, AREMA 4a and AREMA 5 ballast. This material is used primarily for railroads as mainline ballast or cross walk material. Because the purpose of Walking Ballast …

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. Rail ballast aggregate is typically 30-50mm aggretate. Hard and tough stone is required for rail ballast. Resists the severe attrition in a railway trackbed environment.
