The static and fatigue behavior of low profile precast concrete sleepers
Low Profile precast concrete sleepers have the same vertical dimension as traditional wooden sleepers and thus offer a promising alternative to replace wooden sleepers on tracks where maintaining vertical alignment is necessary. The structural response of Low Profile precast concrete sleepers was …

Condition assessment methods for prestressed concrete railway sleepers: feasibility for South African applications
Concrete sleepers are a key component of railway systems, with estimates showing between 20 million to 35 million currently installed within the South African railway network. The condition assessment of concrete sleepers in South Africa poses a challenge for two main reasons: the scale at which …

Evaluation of the residual prestress force in aged railway concrete sleepers considered for reuse
… 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 primary running lines for second-hand use …
