· According to Brian Solomon's book Railway Maintenance, The Men and Machines That Keep the Railroads Running, today the typical layout for a well-ballasted railroad track system is stone lined to the top of the railroad ties …
· Ballast is a free-draining granular material used as a load-bearing material, which forms the largest component of a rail track by weight and volume. Ballast materials usually include dolomite, rheolite, gneiss, basalt, granite and quartzite (Raymond, 1979). It is composed of medium to coarse gravel
· Based on the Turkish and international railway ballast specifications, all railway basalt aggregates fulfil the specification requirements for the use in all types of railway applications (Table 7). When the data given in Table 7 and basalt used in this study were compared, it was found that all samples could be used as ballast materials.
· 2.1 Ballast, Capping and Subgrade characteristics The fresh ballast used in the present investigation is Latite Basalt, a common ballast aggregate obtained from a designated quarry in Bombo (near Wollongong city), Australia. The particles represent sharp angular coarse aggregates of crushed volcanic basalt (latite),
· track ballast, the railway has to rely primarily on natural resources and/or geologically developed structures. Track ballast is produced by blasting, breaking-down and ... n Basalt Basalt is a basic volcanic igneous rock occurring as watery lava when it erupts at the earth's surface. It consists primarily of a
The ballast consisted of crushed basalt, and the sub-ballast a well-graded sand with gravel, meeting the requirements specified in the AREMA Manual for …

the railway track, by damping the vibrations caused by the vehicle tra c and allowing water drainage. Several minerals can be used, including either metamorphic rocks, such as serpentinite, amphibolites, and gneiss, or volcanic rocks such as basalt, porphyry, and trachyte [1]. Over time, mainly due to abrasion and wear, ballast
Railway ballast. For many years Deutsche Bahn AG and numerous contractors involved in permanent way works have been putting their faith in Basalt-Actien-Gesellschaft as a competent partner and supplier of high-quality railway ballast.
Track ballast is usually mined regionally and therefore reflects the colour of the rocks and stones in that region. With the new types of ballast by NOCH, you can, among other things, ballast your track beds extremely realistically. The ballast is available in four different colours and two different grain sizes for H0, TT, N and Z gauge.
· Railway ballast is a mass product. To build one kilometre of railway line some 7,000 tonnes of ballast are required (Österreichische Bundesbahnen (ÖBB) 2002). Austrian Railways alone have an annual demand of some 1 million tonnes p.a. (Kuttelwascher 2011).
· Railway Technical Website Page 2 Updated 10th May 2017 track itself is supported on "ballast", made up of stones - usually granite or, in the US, basalt - below which is a layer of sand, which separates it from the formation. For new or renewed formations, the sand is normally laid over some sort of geotechnical screen
· ballast. Keywords: Ballast, Railways, Hardness, Los Angeles, Deval, Cleanliness, UIC, Basalt, Limestone, Civil engineering, Senegal. INTRODUCTION . Transport infrastructure has an important role in a country's economic and social development. They essentially include the three sectors: land (road and rail), seawater and air. The railway
· Four types of railway ballast materials (i.e. basalt, marl, dolomite and trachyte), rounded river aggregate and degraded ballast sample gathered from railway track were analyzed by the developed image processing method. In summary, the number of images taken from various views for each specific aggregate was determined according to considered ...

For Senegalese public works, Diack Basalt is a good material for railway ballast. Typical transverse profile adopted for Regional Express Train (TER) in Senegal [21] Results of granulometric tests
· ballast deformation and degradation under different con-ditions. A flowchart of the experimental programme, conducted by the authors on railway ballast based on large-scale triaxial testing, is shown in Fig. 1. Ballast behaviour. Ballast is a free-draining granular material used as a load-bearing material in railway tracks. It is composed of ...
· Degradation of railway ballast aggregate is ensued from breakage of single particle as well as from abrasion of angular corners. The present study evaluates the change in morphological characteristics as well as particle size distribution of ballast aggregate degraded under applied impact loads to further illuminate the degradation mechanism of particles.
· real railway ballast and sand. 1 INTRODUCTION The railway track is a layered foundation made of several layers: railway ballast, com-pacted sub-ballast and form layer, followed by an embankment or formation soil. Railway ballast is an uniformly graded coarse granular material that is placed underneath and be-tween track sleepers.

Based on the results, basalt aggregates have higher shear resistance than SSA for all normal stress. However, steel slag has sufficient shear strength as well as particle abrasion resistance. Overall, it was proven that the SSA has suitable stability against shear forces that could be applied on railway ballast.
· The railway track elements (iron rail bars, concrete sleepers, crushed stone layers, base or ballast layer and the subgrade layer) play an important role to resist the stresses resulting from the movement of trains on this track line, the basic purpose for the railway components to transfer resulting stresses safely to earth's natural layer.
