Railway ballast performance is dictated by a complex mix of mechanical properties. These
effect its performance at the particle level for example in terms of particle degradation, but …

Keeping railway tracks in good operational condition is one of the most important tasks for
railway owners. As a result, railway companies have to conduct track inspections …

Crushed stone from natural sources is commonly used as ballast in railways. The material is
a good ballast, but its extraction is destructive. Therefore, this study characterizes basic …

A ballasted railway track is contaminated when passes through sandy areas. Due to sand
penetration into the ballast voids, mechanical behavior of tracks deteriorates. Despite the …

Ballast fouling occurs when the voids of granular particles are wholly or partially filled by fine
particles. Railway ballast fouling is always an inevitable issue related to railway …

With an emphasis on the combined degradation of railway track geometry and components,
an improved numerical approach is proposed for predicting the track geometrical vertical …

Ballast is a layer of the railway infrastructure that ensures the correct geometric position of
track equipment, distributing vertical loads on the underlying layers. Ballast is composed by …

Railway infrastructure is a complex asset and must have a long service life. Therefore,
effective maintenance methods are required to achieve optimal results throughout the life …

With an emphasis on the combined degradation of railway track geometry and components,
an improved numerical approach is proposed for predicting the track geometrical vertical …

Railway ballasted tracks, when exposed to prolonged sand intrusion, exhibit significant
changes in the fundamental mechanical properties. This study undertakes a comprehensive …
