A Review of Numerical Models for Slab-Asphalt Track Railways

Higher train speeds and heavier axle loads trigger elevated stresses vibrations in the track, potentially increasing track deterioration rates maintenance costs. Alternative forms made of combinations reinforced concrete asphalt layers have been developed. A thorough understanding slab tracks is needed to investigate performance. Thus, analytical numerical models developed validated by many researchers. This paper reviews railway The synthesis major finite element described detail, highlighting main components their outputs. For models, use a structural layer within remains an active research topic firm conclusions on its efficacy are not yet available. It can be expected that structures will also affected train-induced ground vibrations. There thus gap literature regarding measurement dynamic effects high-speed lines, further behaviour slab–asphalt systems. In this review, novel solutions for mitigating rail discussed compared. material railways appears beneficial effects, such as bearing capacity stiffness structure improving performance responses, particularly under loads.
