Geology/Track Ballast - Alternative Materials.


Dear Agarwal

Which could be the alternative materials which can be used / tried out instead of Ballast or crushing stones ?. viz Cement, plaster of Paris, sand, coal, metal, non metals etc for railway tracks ?.

If we create a Word Document having a table consisting of the columns Materials,Advantages,Disadvantages and Conclusion,
Can this be a Good reference document for evaluation ?.

Awaiting your reply,

Thanks & Regards,
Prashant S Akerkar

Dear Mr. Prashant, some of the requirements of ballast are :
Hard rock un altered that can be broken easily into fragments with sharp edges and it should be available cheaply as near as possible.

so it may vary from site to site depending upon availability.

I  basalt country, basalt is the ideal choice, in granite/gneissic  country, granite and gneisses are the ideal choice. While in quartzite country it would be quartzite.

I do not think plaster of paris, cement, sand, coal metals and non-metals qualify for use as be ballast.
