Evaluation of the residual prestress force in aged railway concrete sleepers considered for reuse
… a conventional railway track is the prestressed concrete sleeper. In South Africa, these sleepers are designed to last for 40 years, and their replacement plan is aligned with their design life. Given the desire to extend the useful life of sleepers, aged concrete sleepers are often removed from …
