The "top" ballastTrack Ballast AmericanRails.comTrack 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).

How to build a railwayRailroad Ballast Southern Crushed ConcreteProduct Description. 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.
Railroad Subgrade Support and Performance Indiorsfactors affect its performance including classifiion properties, moisture content, shear strength, consolidation, and stiffness parameters. Ballast fouling, ballast pockets, pumping of soil fines through the ballast, and slope stability failure are all issues that can arise as a result of poor subgrade and drainage conditions.DEVELOPMENT OF A FOREST ROAD WITH A NEWLY But in the latest road building (1996), a newly devised, coarsemeshed and hinged wire net was used for stabilizing the ballast to overcome the abovementioned weak point. Future problems. It seems that there is a clear relationship between the declining curve of the drained water after rainfall and the permeability of the subbase.

The year in which Ballast Nedam showed positive results for the first time in seven years. Read MoreGeotechnical properties of ballast and the role of maximum track stability the ballast needs to be angular, well graded and compact, which in turn reduces the drainage of the track. Therefore a balance needs to be achieved between bearing capacity and drainage. To elucidate this point, the main geotechnical properties of ballast are briefly discussed in this section.
