Introduction to Railroad Track Structural Design

Ballast quality and ability to resist crushing forces (ballast degradation is the number 1 cause of ballast fouling) Some railroads use different track modulus (u) values in design. For example, Spring u may be used for rail bending and ballast depth, but Winter u used for rail seat forces. Other railroads may use a

Tamping machine Wikipedia

A tamping machine or ballast tamper is a machine used to pack (or tamp) the track ballast under railway tracks to make the tracks more durable. Prior to the introduction of mechanical tampers, this task was done by manual labour with the help of beaters. As well as being faster, more accurate, more efficient and less labour-intensive, tamping machines are essential for the use of concrete

Unit weight is a measure of the weight of a unit volume of material. There are two basic measures of density or unit weight applied to soils Dry density is a measure of the amount of solid particles per unit volume. Bulk density is a measure of the amount of solid + water per unit volume. The preferred units of density are Mg/m³, kg/m³ or g/ml.
