The Perfect AREMA Ballast. AREMA Ballast (4, 4a, & 5) is also known as ballast stone, railroad ballast, walking ballast, mainline ballast, shortline ballast, and yard ballast, This material is used primarily for railroads as mainline ballast or cross walk material.Because the purpose of AREMA Ballast is to improve drainage. Ordovician Dolomitic Limestone is the perfect source material.

track ballast crushing line is a kind of new mobile crushing plant, which combines many equipment together by vehicular way. Mobile crushers are widely used for crushing mineral ores or stones, recycling construction wastes, producing aggregate and building highway or railway, etc.

Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.
