07/03/2005· The depth of ballast also tends to vary with the density of traffic, as faster and heavier traffic requires greater stability. The quantity of ballast also tends to increase over the years as more and more ballast is piled on. Some figures from an 1897 report are: first class line – 60 lb/yd (29.8 kg/m) railGeotechnical properties of ballast and the role of,,two properties that play pivotal roles in rail track safety. Bulk density is a function of the particle specific gravity and the void ratio. Two methods can be employed to increase the bulk density: the use of denser particles, and a broader gradation. Ballast with higher specific gravity can improve the strength and stability of railway track, increase durabil-ity under cyclic loading, and,Railway Track Ballast - Cloburn - UK Wide Delivery!,Granite is becoming more and more popular in its use for track ballast as it’s density and strength mixed with its angular shape make for a hard-wearing rail ballast that can stay strong for decades.
