Track ballast - Wikipedia

Track ballast should never be laid down less than 150 mm (6 inches) thick, and high-speed railway lines may require ballast up to 0.5 metres (20 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil , and in unfavourable conditions, overloading the soil causes the track to sink, usually unevenly. [5]

Railway Ballast Function Of Stones In Railway Track

Railway ballast or track ballast refers to crushed stones placed under the railway track. It forms the trackbed for sleepers to lay on. Although some tracks are ballastless, the ballasted track remains a dominant infrastructure of the most railroad tracks. Why is that? Ballast in railway may seem inconspicuous, but its function plays a key role.

RAILROAD BALLAST SIZING AND GRADING

Railroad ballast gradings tend, not only in North America but also world wide, to be uniformly graded (i.e., single sized with the opening of the major percent passing sieve being 1.5-3 times the size of the percent retained on sieve). Herein a laboratory examination of ballast top size and grading are made in the triaxial apparatus.

Why Crushed Stone ( ballast ) Are Placed In

Track ballast is typically made of crushed stone, although ballast has sometimes consisted of other, less suitable materials, for example burnt clay. The term “ballast” comes from a nautical term for the stones used to stabilize a ship. Track ballast forms the track bed upon which railroad ties (sleepers) are laid.
