Railroad Ballast

Railroad Ballast

Railroad ballast is produced by first blasting solid rock from the quarry face. It is then crushed and screened to produce an open graded product. This differs from the well graded products, such as concrete aggregate, in that the stones within the product are all close to the same size. This reduces the effect of the filling in of the voids between the stones by smaller particles. The open gradation allows water to drain through and away from the tracks on the subsurface below. Ballast is placed around and under the railroad ties and tracks and helps to support and level the track. Ballast also helps to inhibit vegetation growth.
