(TU Delft Railway Engineering) Contributor Calçada, Rui (editor) Kaewunruen, Sakdirat (editor) Date 2022 Abstract Railway ballast is normally made of crushed rocks with grading (particle size distributions). Ballast is inevitably suffering from more rapid degradation. Because ballast keeps undergoing and dissipating most of the train loadings, furthermore, the train speed and freight weight are increasing, causing more intensive loadings to ballast. To prolong ballast service time and reduce ballast maintenance cost, more studies need to be performed on the ballast degradation reduction, ballast inspection, and ballast assessment. Therefore, earlier distinguished studies on these three aspects are introduced, summarized and discussed in this chapter, toward the final goal of providing research gaps, engineering guidance, and maintenance advice.
