Prestressed Concrete Sleepers – Duraset
Duraset Sleepers are manufactured with 60MPa concrete, reinforced with high tensile prestressed wires. This enables the sleeper to perform even under the most adverse railtrack conditions. The 1:20 built-in cant provides proper rail-to-wheel contact, ensuring optimum performance. Cast-in shoulders ensure consistent, accurate track gauge.

Nonlinear finite element modelling of railway prestressed
Three-dimensional nonlinear finite element model of railway prestressed concrete sleeper has been developed in this study. The general purpose finite element package, ANSYS 10, is employed for the numerical analyses. Using SOLID65 solid element, the compressive crushing of concrete is facilitated using plasticity algorithm while the concrete cracking in tension zone is accommodated by the

Concrete sleeper
Interest in concrete railway sleepers increased after World War II following advances in the design, quality and production of pre-stressed concrete. Chaired bullhead concrete sleepers have been around since at least the 1940s; the Great Western using a two-holed chair, thus saving both scarce wartime timber and steel fixing bolts. [4]

Full-scale static and single impact testing of prestressed
For the conventional prestressed concrete sleeper, a sudden drop in load capacity was typically observed due to severe local crushing in the extreme top fibres and steel reinforcement fracture. Based on the number of steel wires failing, an abrupt yet partial or complete loss in load capacity was observed in PO-S1 and PO-S2 specimens respectively.

Structural behaviour of prestressed concrete sleepers
A comparative analysis of the structural behaviour of prestressed concrete sleepers made with high performance concrete (HPC) and high performance recycled aggregate concrete (HPRAC) is presented in this study. Two types of HPRAC sleepers were tested, using 50 and 100% of recycled concrete aggregate (RCA) in replacement of coarse natural aggregates. The RCA employed in this research was

Design of Prestressed Concrete Sleepers
Design of prestressed concrete sleepers. The basis for design work for prestressed-concrete sleepers in Europe is EN 13230, valid since October 2002: “Concrete sleepers and bearers.”. A supplement to this standard is UIC 713: “Design of Monoblock Concrete Sleepers,” which provides a design example for a prestressed-concrete sleeper.
