It is essentially a cradle to grave look at the life of a product. LCA investigates: raw material extraction production and manufacture usage and reuse disposal or end of product life By using LCA, Austrak is able to determine the most sustainable way to supply, produce and manage the life of a sleeper or turnout. This analysis will show alternative means of raw material supply, potential increases in manufacturing efficiency, reuse and recycling possibilities and outcomes of product end of life. This encourages an extensive look at the sustainability and environmental effects of sleeper manufacture. [1 of 3] DISCLAIMER

These forces act to reduce any applied tensile forces allowing PC to be used in situations where bending stresses occur. Sleepers are exposed to repetitive bending stresses in a railway track and as such the use of PC is an excellent example of combining a material like concrete, which is suitable for mass production, with high-strength steel to provide the required tensile capacity. PC sleepers are produced in a pre-casting operation where rapid production rates combined with quality control processes can produce the large numbers of PC sleepers required to the specified tolerances needed for railway track construction. A precast PC sleeper is an “engineered” product where the structural and materials engineering processes are used to produce a sleeper that has the required strength and durability for the intended application. Quality management of the raw materials and processes, along with in-process and final product testing, ensures that each sleeper is produced to the tolerances required. [1 of 5] DISCLAIMER
