Optimum design of composite prestressed concrete girder railway bridges [PDF]

, 2012
This paper deals with the formulation of design optimisation of pretsressed concrete bridges. The bridge is of a slab-on-girder type, hence modeled as an equivalent orthotropic plate.

Improving the performance of railway tracks through ballast interventions

, 2018
Maintenance and eventual renewal of a ballasted track constitute major operational costs for a railway network. Thus, significant benefits would accrue from a more robust track design having a longer service life and reduced maintenance requirements ...

Microgrid reinforcement of scaled railway ballast

E3S Web of Conferences
Ballasted tracks are predominant on railways worldwide. Previous research on random fibre reinforcement of scaled ballast has shown that flexible polymeric fibres can increase the shear resistance and ductility of the ballast. Owing to the difficulty of testing very coarse materials in standard laboratory apparatus, scaled-down materials have been ...
