Indian railways (IR) for railway ballast . In contrast, no evidence has been found regarding rail- road application of SFS in Europe or relevant research on this topic. Hence, according to Ref. , in 2012 the uses of SFS were road construction (43 %), interim storage (19 %), ﬁnal disposal (13 %), metallurgical purposes (11 %), cement production (5 %), hydraulic engineering (3 % ...

This European Standard specifies the properties of aggregates obtained by processing natural, manufactured or recycled crushed unbound aggregates for use in construction of the upper layer of railway track. For the purposes of this standard, the aggregate is referred to as railway ballast.
Ballast degradation was significantly reduced by increasing the coefficient of uniformity of ballast aggregates. But it increased when the overall aggregate size was increased due to the significant corner breakage and attrition occurring in larger sized aggregates.
International Classification for Standards (ICS) is an international classification system for technical standards. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used.

The standard rail sections in use on Indian Railways are 60 kg, 52 kg, 90 R, 75 R, 60 R and 50 R. The two heavier rail sections, 60 kg and 52 kg, were recently introduced and are designated in metric units.
Abstract. This article presents an overview (requirements) of rail track aggregates, the ballast gradation adopted in railways in different countries and their comparison with Indian ballast gradation, drainage of rail track and ballast fouling in India.
requirements used when supplying aggregates for use in Railway Ballast applications. Aggregate produced from rock, gravel, metallurgical slag or synthetic materials may be used provided the particular criteria set out for the aggregate are met. AS 2758.7 sets out the requirements for the quality of a material source and the properties required of the rock. This Standard sets out best practice ...
Rail Track Ballast is an essential part of any rail construction project. Rail Track Ballast is typically made from crushed granite which has been screened to remove undesirable fines thus creating a hard wearing, free draining and easily cleaned aggregate. Typically Rail Track Ballast is packed between, below, and around the sleepers by specialised equipment. It is used to facilitate drainage ...
