This study describes the structure of non-ballasted track, focusing on design approaches for non-ballasted track, the structural parameters of non-ballasted track, and the advantages and disadvantages of ballasted and non-ballasted track. A systematic review was conducted by searching reputable national and international articles on non-ballasted track structures in leading databases using the article keywords, followed by full-text screening and classification of the selected articles. The components of non-ballasted track comprise the rail, fasteners, rail support platform, prefabricated concrete slab, cement asphalt mortar layer, and concrete base. Ballasted and non-ballasted track systems have distinct technical, economic, and environmental advantages and disadvantages, and the choice between them depends on line speed, construction cost, maintenance requirements, and the targeted service life.
