Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
2018-9-9 Railway ballast can be defined as a homogeneously graded material coming from the crushing of hard rocks or, seldom, of coarse gravel with small-sized particles sieved out. A railway track bed structure made of ballast aggregate particles is typically laid on the subgrade directly.
Therefore, such stockpiles of waste ballast may result in safety issues for the staff driving on rail access roads and moreover, may damage the drainage paths around the railway
2020-10-13 The ballast and its engineering behaviour have a key role in governing the stability and performance of railway tracks. The deformation and degradation behaviour of ballast under static and dynamic loads was studied based on large-scale triaxial testing. The possible use of different types of geosynthetics to improve the performance of fresh
2020-8-20 Ballast is the granular material that distributes the cyclic loads induced by trains to the underlying track structure. The size of the aggregates is usually comprised between 20 and 62 mm . Ballast is commonly adopted as the primary load bearing component and represents the track form most used in Norway .
This invention concerns a machine to clean and rehabilitate railway ballast and railway road beds. To be more exact, the invention concerns a cleaning machine which is known in itself and can also perform rehabilitation operations on the railway road bed when necessary

2021-7-3 Track ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and to keep down vegetation that might interfere with the track structure. The ballast also holds the track in place as the trains roll over it. It consists of crushed stone.
2011-1-1 Available online at sciencedirect The Twelfth East Asia-Pacific Conference on Structural Engineering and Construction Railway Ballast Diagnose through Impact Hammer Test H.F. Lama and M.T. Wongb,1 aDepartment of Building and Construction, City University of Hong Kong, HKSAR, China bMTR Corporation, Hong Kong Abstract This paper reports a feasibility study in the use of measured modal parameters of in-situ concrete sleepers to detect possible damage of the underlying railway ballast.
The results of the laboratory tests are commonly used to reject or accept material for use as ballast and rarely imply benefits or costs of selecting alternative materials or gradations. In this paper are presented the results of a track sampling and evaluation program to determine the performance of ballast, subballast, and the subgrade on Canadian Pacific (CP) Rail.

2019-11-11 The use of railway transportation systems has been increased throughout the years. The conventional ballasted tracks have been used widely in many countries around the world. Ballast material is the basic element of ballasted tracks. Ballast degrades and deforms after service. Therefore, periodical ballast maintenance is needed which is a cost and time expensive activity. Understanding ballast
The tensile strengths of six types of ballast for various size fractions were investigated and quantified using Weibull statistics. For a given ballast and a given size fraction, the strengths follow the Weibull distribution reasonably well. However, it was found the size effect on strength implied by Weibull statistics for bulk failure of particles, is not consistent with measured values
