of ballasted track of different stiffness sections using polyurethane ballast reinforcement technique QI Wei, LIU Yutao, LI Chenghui (Key Laboratory of High-Speed Railway Engineering, Ministry... track. The degradation is aroused by the abrupt variation of the track stiffness which is led by the vertical settlement of the track. In order to solve these problems, the polyurethane ballast......
and galvanized iron, three blank thicknesses of 0.6, 1.1 and 1.5 mm, and two Teflon-fillers of PVC and polyurethane are used in several experimental tests. In the analytical part, theoretical deformation models.... Furthermore, experimental observations illustrate that forming energy of a certain blank with PVC Teflon-filler is higher than that of a similar specimen with polyurethane Teflon-filler......
