During the development for railway, ballasted track is dominant structure and makes up
more than 95% of the whole track modes. However, its shortage is considerable in high …

Ballasted railway tracks, despite their benefits, present some limitations and drawbacks,
mainly associated with geometry degradation due to ballast settlement and particle …

Red clay, a widely distributed soil, weakens significantly when exposed to water. This poses
challenges for using it as a foundation for urban infrastructure, as rainwater scouring …

Railway ballast degradation under dynamic loads progressively leads to loss of mechanical
performance and geometry of the track, so that maintenance interventions are frequently …

Ballast degradation is frequently observed under cyclic loading, and results in bearing
capacity and drainage problem of ballast track. To keep the stability and safety, periodical …

In the recent past, the use of polyurethane polymers to stabilize the ballast is on rise. This
paper presents a critical review of different polyurethane stabilization techniques used …

Railway track components located at bridge transition zones or approach areas suffer from
impact load and vibrations caused by abrupt changes in track stiffness on the bridge and the …

Bitumen stabilized ballast (BSB) is a novel and promising construction or maintenance
strategy of traditional ballasted track-bed that consists in the use of bitumen emulsion (BE) …

Expensive and time-consuming maintenance operations are routinely performed to preserve
the ballast mechanical properties in railway lines. Binding agents are used for ballast …

Despite being the most used worldwide, railway ballasted tracks presents high maintenance
cost related to ballast settlement and particle degradation. With the aim of reducing life cycle …
