Effects of Principal Stress Axis Rotation on Unsaturated Rail Track Foundation Deterioration
Procedia Engineering, 2016 AbstractPrecise assessment of cyclic plastic deformation of rail track subgrade is essential in designing cost effective rail tracks. Plastic deformation of rail tracks is often underestimated due to the omission of effects of principal stress axis rotation and water content on subgrade deformation. Moisture content of rail track subgrade is influenced

Soils and Foundations, 2012 AbstractIt is generally observed that the stress state induced through traffic loads inside the substructure of pavements cannot be exactly reproduced in laboratory element tests. Moreover, there are not sufficient studies that examine the behavior of granular material under unsaturated conditions, although such conditions are very prevalent in ...

Soils and Foundations, 2017 Cumulative plastic deformation of rail track subgrade materials under moving wheel load is a complex problem. The plastic deformation and resilient modulus of subgrade material subjected to moving wheel load are a function of Principal Stress Axis Rotation (PSAR). Difficulties associated in controlling PSAR in the conservative experimental methods lead

Transportation Geotechnics, 2021 Abstract Current Japanese design guide uses mechanical-empirical criteria to predict the failure loading number against fatigue cracking and rutting. However, these criteria have some limitations that the variation in moduli of base and subgrade layer due to the fluctuation in water contents, freeze–thaw history, and stress states are not considered.
