Railroad Ballast Particle Breakage with Unique Laboratory Test Method
Acta Technica Jaurinensis, 2019 This paper demonstrates the results in the research topic of the railway ballast particles’ breakage test with unique laboratory test. The most railway lines in the world have so called traditional superstructure (ballasted tracks). In the past few years

An investigation into the railway ballast grading using GPR and image analysis [PDF]
, 2017 This study reports on an investigation into the grain size distribution of the railway ballast using ground-penetrating radar (GPR) and image analysis. The proposed approach relies on the hypothesis that the dimension (grading) of the ballast aggregates ...

Remediation of Mud Pumping on a Ballasted Railway Track [PDF]
Procedia Engineering, 2016 AbstractMaintenance of ballasted railway tracks is a major cost for railway infrastructure owners. In many developed countries, much of the railway infrastructure is mature and was built for service requirements long since superseded. The increased demands on historic infrastructure can lead to the development or exacerbation of localised trackbed ...

SPECIFIC ASSESSMENT METHOD OF RAILWAY BALLAST PARTICLE DEGRADATION BASED ON UNIQUE LABORATORY TEST
Nauka ta progres transportu, 2018 Purpose. There are specific, standardized laboratory test methods to assess railway ballast particle degradation; they are the Los Angeles (EN 1097-2) and the Micro-Deval abrasion (EN 1097-1) tests. These testing methods can’t take into consideration the
