Over 3 million tons of Texas Crushed Stones crushed limestone has been used for railroad ballast. Railroad ballast is typically graded from 1 ¾ or 1 ¼ to ½. Ballast is open graded and washed over a screen as part of the production process. Railroad Ballast supports the railroad ties. Because ballast is a large onesize, angular rock, it allows water to drain away from the track.
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.
Ordovician Dolomitic Limestones physical properties enhance drainage and its interlocking shape helps to stabilize and disperse the load of the overall track structure. Walking Ballast in Agricultural Construction. Walking Ballast is very effective when used as a base for agricultural construction.
Limestone Ballast. Limestone aggregate is often chosen as the limestone ballast used to support the rails in railway construction. As with roadbuilding, limestone aggregate is popular with track layers due to its strength, durability, and excellent drainage-promoting qualities.
Rail track ballast serves as a bed for rail tracks and provides drainage and strength for heavy loads carried by trains.
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.
Railroad ballast is one of the most demanding applications for crushed stone. Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage,
May 20, 2013· Limestone is softer than granite or basalt, but it is still quite serviceable for road base and railroad ballast. The choice for railroad ballast depends on cost of material and transportation, and the cost of maintenance such as cleaning and resurfacing for

The stone to be used as railway ballast should be hard, tough nonporous and should not decompose when exposed to air and light. Igneous rocks like quartzite and
Results show that, with the same track superstructure and subgrade condition, the rail support modulus of test track in steel slag ballast section is 1.64 times greater than that of limestone ballast, and the compressive contact pressure of sleeper and ballast in limestone ballast was almost 1.39 times greater than steel slag ballast.
