"General requirements for ballatless rail-trackforms; asphalt and concrete pavement design"

Ballastless railway track-forms use long term experience from road pavement design and construction. Like other special pavements, e.g. airside pavements, the impact of load regimes with respect to service conditions and design life must be carefully studied and reflected by a sound and sustainable pavement design approach. Ballastless track design has to implement rail infrastructure requirements with respect to reliability, availability, maintainability and safety. Ballastless track design must study static and dynamic train loads, load distribution within the structure, environmental impacts, substructure performance as well as interactions with safety and signaling equipment. General requirements and recommendations are highlighted for design and installation of such pavements used as a subsystem to provide long-term bearing capacity for rail track-forms.
