Railway Ballast: What Is It And Why Is It Used? - Building

Railway ballast is an aggregate made up of crushed granite rocks. It is used to create a level and strong foundation for rail tracks and sleepers. It consists of 30-50mm angular stones and is sieved to remove fine particles that are not as durable. Ballast is tightly packed below, between, and around the tracks.

Functions. This brings us onto the functions of the ballast, once it is put down on the railway. It distributes the load of the passing trains from the rails and sleepers above it into the formation sand ground below it. It further spreads the load. It allows water to drain through it, into either the underlying ground or the track drainage.
