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 …

Railway tracks experience stress during train passage. Understanding these subgrade
stresses is essential for the design of track foundations and assessing their serviceability …

The shape of soil particles influences asphalt, concrete, and soil behavior. The image
analysis and visual comparison methods are commonly employed to quantify the shape …

Ballast layer is a part of railway foundation that its behavior is affected by the properties of
constituent particles. The shape of the particles, which affects ballast behavior, is an …

Ballast aggregate is a natural material widely used in railway lines. Its mechanical properties
and particle geometry are meticulously defined using well-established standards and …

A series of large-scale direct shear tests were conducted to investigate the behavior of
unreinforced and geogrid-reinforced ballast at different rates of shearing. Fresh granite …

The effective functioning of a railway track under operating conditions depends largely on
the performance of various rail track interfaces (eg ballast-subballast interface, subballast …

Aggregate shape characteristics play an important role in the performance of the aggregate
materials. The type of crusher and rock may play an important role in aggregate shape …

Railway ballast deteriorates over time due to cyclic loading and environmental factors,
necessitating its replacement to maintain track stability. However, the potential shortage of …
