Utilizing these waste materials in the ballasted railway track will contribute to sustainable develop- ... have investigated the possibility of substituting slag ballast instead of stone ballast in railway tracks. In 2020, Jing et al. ... and ballast tamping. This new geo-grid can reduce environmental pollution by using the waste tires, but it ...
Two types of track can be used: ballasted and ballastless. In the first, the rails sit above concrete sleepers, which distribute the load on a bed of ballast; instead, in the second case, the rails are supported by concrete slabs (Rempelos, et al., 2020).
The acquisition and transportation of aggregate exacerbate the negative impact of concrete on the environment, and waste materials are considered an effective solution to this crucial problem. One of these waste materials is waste ballast (WB), which is needed for new infrastructure along with increasing rail track technology. In this study, the effect of WB …
1. Broken stone Ballast. 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.
Ballast provides stable support and load transfer for railway tracks. Ballast is also used to help drainage of water, keeping water away from the rails and sleepers, as well as keeping down vegetation that might interfere with the track structure.
Steel manufacturing furnace slag is one of these waste materials that railway engineering has utilized as ballast and sub-ballast in recent years. Studies suggest that the ballast layer can utilize steel slag either alone or in conjunction with stone materials.
Railway ballast is typically a layer of coarse, angular stones or gravel that is also called macadam which is a part of the railway superstructure. It forms the base upon which the railroad ties or sleepers are laid.
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 …
Moreover, the use of steel slag as railway ballast is anticipated to reduce the cost of ballast/track construction as the same is freely available from the steel industry. However, the problems of volume expansion and leaching of heavy metals are to be addressed before using steel slag as railway ballast.

Rail ballast: conclusions from a historical perspective P. Claisse and C. Calla Although it is now universally accepted that good-quality hard angular stone of nominal size 40 50 mm is the best material for ballast, historically track has been for longer on non-stone ballast than on stone ballast. Even the stone ballast speci ed up until the ...
The ballast used on branch lines, in yards, and on industrial spurs may be broken stone and/or slag, but more often it's cheaper materials like gravel, cinders, sand, and chats (waste from lead-zinc mining).
One of these waste materials is waste ballast (WB), which is needed for new infrastructure along with increasing rail track technology. In this study, the effect of WB aggregate (w hich is basalt -
