Long-Term Performance Assessment of a Geosynthetic-Reinforced Railway Substructure

Significant savings in carbon emissions, cost, and time could be achieved via the reduction maintenance frequency, capital costs of track construction, land used. Geosynthetic-reinforced soils offer such sustainable solutions. The experimental work presented this paper investigates long-term performance a Geosynthetic-Reinforced Soil Retaining Wall (GRS-RW) system as an alternative to conventional railway embankment. Full-scale testing was carried out on three sleeper sections ballasted slab tracks by simulating train loads cyclically, phased 360 km/h. were supported either low-level fully confined embankment or GRS-RW substructure. substructures formed 1.2 m deep subgrade frost protection layer, accordance with high-speed design standards. overall aim assess tracks, terms transient displacements total settlements. It observed that once reached its active state, it deformed very similar way despite fact is less than results indicate cumulative settlement track, which due plastic deformation soil, significantly primarily caused movement ballast particles.
