Railway ballast stabilising agents: Comparison of

2020-8-20  1. Introduction. 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 .. Ballast aggregates undergo wearing and

Railway Ballast Characteristics, Selection Criteria and

This work is a comprehensive investigation to find to what extent simple laboratory tests e.g. Los Angeles abrasion and micro-Deval might be suitable for predicting real railway ballast performance with respect to deformation and degradation. A number of tests to measure essential properties of ballast aggregate have been performed in addition to advanced material testing.

High performance bituminous sub-ballast for improving

2021-5-4  Materials. Two different binders were studied for the creation of the high-performance bituminous sub-ballast layer: a conventional B50/70 bitumen (CB) was used as a reference, having been commonly used in previous asphalt railway tests [9, 20]; and a modified, low-penetration bitumen containing rubber from out-of-use tires (MB).The latter bitumen is a

Advanced characterisation of railway ballast roundness

The performance of a railway track structure is significantly influenced by ballast shape properties such as roundness, flatness, elongation, sphericity, angularity and surface texture. Railway ballast materials have to comply with several quality requirements and shape properties.
