The properties of railway ballast material are affected by the local geologies and climatic
environments from which the parent rock is sourced. These factors can make it challenging …

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 …

The disposal of waste tyre rubber (WTR) is an environmental challenge, and a significant
amount of waste is sent to landfills. However, modern railway tracks depend on rubber …

The stock of disposable face masks has climbed steadily due to COVID-19, which results in
an urgent worldwide environmental problem. This investigation aims to assess the potential …

Applying traffic load to railway tracks as well as tamping operations results in ballast
deterioration. To tackle this problem, several solutions have been proposed in the literature …

The railway ballast layer provides the function of bearing loading, resisting geometry
degradation, and drainage. In those related research, the behaviour of ballast assembly can …

Parent rock strength and crumb rubber modification are two critical mechanical parameters
that significantly decide the ballast layer degradation subjected to train dynamic loading …

Scrap tyres are used to produce tyre-derived aggregates (TDA), which can be used as fill
material, backfill material, drainage layers, and vibration-damping material, among other …

Tunnels may be constructed in a pair undercrossing existing geotechnical structures
exposed to cyclic loading. Such construction changes the stress state in the ground in …

Soft subgrade poses a significant design challenge for railway projects because of its high
compressibility and low shear wave velocity. Therefore, it is important to increase its stiffness …
