BS EN 13230-2 is the second part of the BS EN 13230 series of standards that discusses about the manufacturing and testing of prestressed monoblock sleepers.
BS EN 13230-2 is a part of the EN 13230 series defines additional technical criteria and control procedures related to the manufacturing and testing of prestressed monoblock sleepers.
BS EN 13230-2 on manufacturing and testing of prestressed monoblock sleepers is useful for:
Prestressed monoblock concrete simply replaced timber, bullhead rails and cast iron chairs being used as in other conventional track. The great advantage of prestressed concrete was that concrete is kept under compression under all conditions of flexure, both under load and after. This means that tension cracks do not occur which can allow the ingress of moisture and corrosion of embedded steel. BS EN 13230-2 specifies production testing and control procedure related to the manufacturing of prestressed monoblock sleepers to ensure that the concrete will not suffer degradation in service through a chemical reaction, frost damage, low cost, high durability, ease in construction, and maintenance.
