Rail Track Maintenance Planning: An Assessment Model [PDF]
, 2000 In Australia, railway track maintenance costs comprise between 25-35 percent of total freight train operating costs. Track maintenance planning models have been shown to reduce maintenance costs by 5 to 10 percent though improved planning.

Prediction of Lifespan of Railway Ballast Aggregate According to Mechanical Properties of it
The Baltic Journal of Road and Bridge Engineering, 2017 As the railway lifespan is the main criterion for selection of the aggregate for ballast and for planning the maintenance of the railroad, it is important to define the relationship between the particle load resistant characteristics and a lifetime of ...

Modelling Experimental Measurements of Fluid Flow through Railway Ballast
Fluids, 2022 The flooding of railway ballasts can cause extensive damage. This process has been the subject of several experimental investigations. In the present work, a relatively easy to implement approach to modelling this fluid flow is presented.

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 ...

Measuring the area and number of ballast particle contacts at sleeper/ballast and ballast/subgrade interfaces [PDF]
, 2015 The number of railway ballast particles in contact with a sleeper may be relatively small. The discrete and non-uniform nature of these contacts may cause breakage and wear.

Railroad ballast behavior in triaxial compression tests with and without geogrid [PDF]
MATEC Web of Conferences, 2019 This paper highlights recent laboratory studies at Emperor Alexander I St. Petersburg State Transport University, using large-scale cylindrical triaxial apparatus, which helped quantify the geogrid performance in railway ballast.

Metabolic and cometabolic degradation of herbicides in the fine material of railway ballast [PDF]
, 2006 Microbial degradation of 3-(3,4-dichlorophenyl)-1,1-dimethylurea (diuron) and mineralization of 4-chloro-2-methylphenoxyacetic acid (MCPA) were studied in soil samples taken from the ballast layers of three Swedish railway embankments. The degradation of

Geophysical characterization of derelict coalmine workings and mineshaft detection: a case study from Shrewsbury, United Kingdom [PDF]
, 2009 A study site of derelict coalmine workings near Shrewsbury, United Kingdom was the focus for multi‐phase, near‐surface geophysical investigations. Investigation objectives were: 1) site characterization for remaining relict infrastructure foundations, 2)

Stress–dilatancy relationship for railway ballast [PDF]
Studia Geotechnica et Mechanica, 2018 Abstract Knowledge of the mechanical behaviour of ballast is very important for designing a railway track, especially for high-speed lines. The monotonic drained triaxial tests of scaled and fouled ballast presented in literature were analysed using the Frictional State Theory.
