Track ballast Wikipedia

Mar 07, 2005 Construction. The appropriate thickness of a layer of track ballast depends on the size and spacing of the ties, the amount of traffic on the line, and various other factors. 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

Size and Section of Ballast in Railway Civil Engineering

The size of the ballast used in railway track varies from 1.9 cm to 5.1 cm. The stone of size larger than 5.1 cm is not preferable due to poor interlocking property. The best-recommended ballast is that which contains stones ranging in size from 1.9 cm to 5.1 cm.

Friction and wear in railway ballast stone interfaces

Nov 01, 2020 This is a much higher stress regime than reported in other works on railway ballast. While stresses at field conditions are hard to access, in laboratory tests on railway ballast,,,, all applied stresses are clearly below 1 MPa. In this work, cyclic friction tests were conducted on railway ballast.
