Rail ballast aggregate is typically 30-50mm aggretate. Hard and tough stone is required for rail ballast. Resists the severe attrition in a railway trackbed environment. Tarmac ballast is typically granite as its strength delivers natural durability., although other aggregate types can satisfy the requirements for trackbed ballast
Verwijder met een kwastje voorzichtig alle ballast die op de verkeerde plekken ligt. De kleine steentjes / korrels willen graag alle kanten op springen, dus geduld is wel een schone zaak.

It should not have any chemical effect on the rails and metal sleepers. It should resist attrition and should be durable. Ballast used should be non ...
Rail tracks are normally positioned on ballast because it is economical (availability and abundance), and because drainage is rapid and the tracks have a high load bearing capacity.
