Dear Jb Tan

Crushed stone, washed gravel, bank run (unwashed) gravel, torpedo gravel (a mixture of coarse sand and small gravel), slag, chats, coal cinders, sand, and burnt clay have all been used as track ballast. Ballast is derived from a nautical term for the stones used to stabilize a ship.

Los Angeles abrasion value and magnesium sulfate freeze-thaw test result should be quite low. For example, it should be below 15%. Because high-speed railways have very strict geometric tolerances. To provide this value, for example, a basalt type aggregate would be an ideal choice.

Qamar Ul Islam Ferhat Çeçen Thank you very much for the valuable information :)

Taşın niteliksel özellikleri önemli olduğu gibi fiziksel özellikleride son derece önemlidir.Agrega gradasyonuna çok dikkat edilmeli. Taşların sağlamlığı ömrünü belirlerken fiziki özellikleri karşı kuvvetlerin oluşmasında önem kazanmakta.
