Change of Ballast Strength Properties During Particles Abrasive Wear

The paper describes cohesion and friction angle research results of new granite railway ballast. It was found out that crushed stone abrasion degree increase leads to ballast cohesion decrease and has not effect on ballast friction angle. Authors determined that strength properties of new and reclaimed ballast mixtures depend on initial abrasion degree significantly. When using a mixture of 70% reclaimed and 30% new ballast it becomes possible to provide mixture ballast strength properties closely approximated to requirements for new ballast.
