operators, designers and manufacturers of railway sleepers with requirements for the specification, manufacture and testing of prestressed concrete sleepers for use in railway track. This Standard does not cover the use of materials complying with superseded editions of the AS 1085 series or the use of existing or re-used materials.
The company is also the country's first ISO certified concrete manufacturing plant. The sleepers manufactured by the company are suitable for the following: Normal Broad Gauge: This sleeper has a trapezoidal cross section having a width of 154 mm at the top and 250 mm at the bottom and a height of 210 mm at rail seat.
Due to the rigidity of the cast-in portion of the rail fitting, a concrete sleeper maintains the rail gauge much better than a timber sleeper, where the increase of gauge over the years is an accepted phenomenon. This applies especially to curved track. ADVANTAGES OVER POST TENSIONED MONOLITHIC TYPES. ECONOMY THROUGH STRENGTH

The value for sleeper density for India is 18, whereas, in the USA, the Value of Sleeper Density is 23-25. Types of Railway Sleepers. The sleepers can be classified into five main categories, generally depending upon the materials of construction: Wooden sleepers; Steel sleepers; Cast Iron Sleepers; R.C.C sleepers; Prestressed Concrete Sleepers ...
Introduction. The traditional materials used to manufacture railway sleepers are timber, concrete and in some cases steel, which are generally designed for 20, 50 and 50 years, respectively [1], [2], [3].Timber was the earliest material used and more than 2.5 billion timber components have been installed worldwide [4].They are adaptable and …
25 Aug, 2022By Catherine Moore. German railway company Deutsche Bahn (DB) is set to complete an inspection of concrete sleepers in its rail network by the end of the month. DB experts have been testing around 200,000 sleepers across the country since July, with repairs expected to cost several hundred million euros.
The old concrete sleepers are crushed and fragmented, creating construction materials in various grain sizes. These can be reused in diverse ways. …

The concrete waste that is taken from broken concrete railway sleeper will be crush as an aggregate as raw material in the concrete to substitute part or all of the …
This study proposed three new railway sleeper concepts for a mainline track and investigated experimentally and numerically to understand their behaviours. ... Concept-3 was designed based on the capacity of GFRP tubes only as the concrete even inside the tubes will crack and crush due to lower ... (however, φ = 2.5 for prestressed …
The length of the B70 sleeper is 2600 mm, the rail seat high is 214 mm, the concrete cover at tensile lob is 50 mm, and the width of the sleeper at the rail seat is 300 mm. The total prestress force implemented during the production of prestressed sleepers is 320 kN. Detailed dimensions are presented in the previous study [16]. In this process ...
In railways, harmonic vibrations occur when there are periodic anomalies such as wheel flats and rail corrugations, while non-harmonic (random) vibrations occur when there are non-periodic abnormalities such as variable sleeper spacing, switches, transitions, and local settlements [2].As it can be seen from Fig. 1 that railway sleepers …

Railway sleepers are crucial structural components of the track, whose primary function is to redistribute the loads (i.e. static & dynamic) to the substructure [1]. Generally, …
The use of concrete sleepers in railways started in the 1940s. They are currently used in many countries thoughout the world at a rate of over 12 million per year. This report discusses the various types of sleeper which have been developed - monoblock, two-block, reinforced and prestressed concrete. Separate sections deal with design, rail fastening …
As the name suggests the basic purpose for the railway components to …A concrete sleeper is a type of railway sleeper made out of steel reinforced concrete. Concrete is good in resisting compressive stress but is very weak in resiting tensile stresses. Hence reinforcement is provided in the concrete wherever tensile stress is expected.
The concrete sleeper is a type of railway track materials. The railway sleeper not only supports the steel rail, but also maintains the position of the rail, and transmits the huge pressure transmitted by the steel rail to the track bed. It must have some flexibility and elasticity. When the train passes, concrete sleepers are properly deformed ...
Rail operations have grown widely and become more demanding. The sleepers are made of conventional concrete and are no longer useable before they reach their anticipated service life of 40 to 50 years. The most common railroad sleeper is the prestressed concrete sleeper [2].

Type B70 concrete sleepers are the simplest way to achieve your finished track. The main advantage of these sleepers lies in their great flexibility. For new rail lines or upgrading of existing tracks, for mainline tracks or urban transport, for trunk or secondary lines, and for freight and passenger traffic: this concrete sleeper offers a […]
The most common types of rail sleepers are wooden, concrete, and steel. Wooden sleepers are the traditional material used for rail sleepers, and they are still used in many rail networks today. Concrete sleepers, also known as concrete ties, are becoming more popular because they are more durable and require less maintenance than …

A prestressed concrete sleeper's fatigue damage is mainly due to the repeated loads derived from dynamic wheel-rail interactions, especially when either wheel or rail irregularity is present.
Concrete sleepers are heavier than all other types hence, gives good stability to the rails. They have long life span so, economically preferable. They have good Fire resistance. Corrosion is not occurred in concrete …

The average timber railway sleeper weighs around 160lb-250lb, whereas an equivalent sleeper made of concrete could weigh anything up to 800lb. This means that wooden railway sleepers are quicker and easier to install initially and require little to no specialist equipment or vehicles for maintenance, which means cost-savings for rail operators.
