As verbs the difference between aggregate and ballast
aggregate deposits are carbonate rock, which is generally considered a lower quality rock deposit for railroad ballast. The key issue on the replacement of ballast is cost with the tradeoff being the quality of the ballast material and the distance to the rail line. The primary objectives of this

Mar 03, 2017 Ballast is an essential layer of the railroad track structure, and provides primarily drainage and load distribution. In general, ballast aggregates are considered as uniformly graded, angular shaped with crushed faces. However, various ballast aggregate gradations and particle shapes are in use yet their effects on ballast performances remain ...
Railroad ballast serves as a bed for railroad tracks and provides track stability, drainage, and support of significant loads carried by railcars. In addition, it deters the growth of vegetation and allows for track maintenance to be performed more easily. Ballast is produced from natural deposits of granite, trap rock, quartzite, dolomite or limestone.
This European Standard specifies the properties of aggregates obtained by processing natural, manufactured or recycled crushed unbound aggregates for use in construction of the upper layer of railway track. For the purposes of this standard, the aggregate is referred to as railway ballast. It incorporates a general requirement that railway ballast shall not release any dangerous substances

The effectiveness of elastomer polyurethane coating of ballast is evaluated for its ability to reduce aggregate breakage and resulting ballast fouling. Railroad ballast degradation and fouling related to aggregate breakdown under heavy axle loads, poor ...
Tamping is a common railroad maintenance activity often used to correct railroad profile. During tamping, tamping arms inserted into the ballast layer raise and loosen aggregates by squeezing and vibrating. As a result, the tamping process may cause serious problems such as derailment due to decreased track lateral stability and track buckle.
