Over time, mainly due to abrasion and wear, ballast loses its mechanical properties and cannot be reused within the rail industry, being sold on to other users to be recycled as an engineering ll material. In the last decade, several cases of railway ballast contamination by organics and inorganic species have been reported [2].
However, ballast deterioration and fouling are major issues in the railroad industry, and can be caused by repeated loadings, which lead to crushing ballast that is in contact with ties. Upward migration of subgrade particles into the ballast layer can increase fouling in the ballast and decrease drainage through the ballast layer.
Ballast cleaning removes this worn ballast, screens it and replaces the "dirty" worn ballast with fresh ballast. The advantage of ballast cleaning is that it can be done by an ontrack machine without removing the rail and sleepers, and it is therefore cheaper than a total excavation.

Other Name(s): Recycled Railway Ballast Consists of: Pure granite crushed. 70/30mm Recycled Rail Track Ballast has been removed from rail track use as part of Network Rail''s track renewal work. The resulting Rail Track Ballast is then rescreened to remove any debris leaving a very good quality recycled rail track ballast suitable for a variety of applications.
Network Rail receives over 1m tonnes of spent track ballast at our Aggregate Handling Depots per annum. This means we have a lot of aggregate for sale. The majority of this material is recycled through screening, crushing and washing processes that make it suitable for reuse in both rail network projects, DIY projects and the construction ...

Aug 30, 2019· The deteriorated ballast was obtained from LAA machine using the fresh ballast. According to standard LAA test procedure (by BS EN 10972:2010 and ASTM C13101), the abrasion process was conducted at a speed of 32 r/min and for 500 rolling the tests, all of the deteriorated ballast was washed, dried, which defined as the recycled ballast.
Track ballast should never be laid down less than 150 mm (6 inches) thick; and highspeed railway lines may require ballast up to 1 ⁄ 2 metre (20 inches) thick. An insufficient depth of ballast causes overloading of the underlying soil, and in unfavourable conditions overloading the .
