Analysis of the influence of cracked sleepers under static loading on ballasted railway tracks

Montalbán Domingo, María Laura; Zamorano Martin, C.; Palenzuela Aviles, C.; Real Herráiz, Julia Irene (Hindawi Publishing Corporation, 2014)

The principal causes of cracking in prestressed concrete sleepers are the dynamic loads induced by track irregularities and imperfections in the wheel-rail contact and the in-phase and out-of-phase track resonances. The ...
Finite element modelling of cracked railway pre-stressed concrete sleepers

Montalbán Domingo, María Laura; Zamorano, Clara; Palenzuela, Cristina; Real Herráiz, Julia Irene (Taylor & Francis, 2014-06)

Loading conditions on railway tracks are the result of the sum of the static axle load of vehicles and augments caused by dynamic effects. Dynamic loads have several causes and can be quasi-static or impacts. Cracking in ...
Mechanical and Physical Properties of Polyester Polymer Concrete Using Recycled Aggregates from Concrete Sleepers

Carrión, F.; Montalbán Domingo, María Laura; Real Herráiz, Julia Irene; Real, T. (Hindawi Publishing Corporation, 2014)

Currently, reuse of solid waste from disused infrastructures is an important environmental issue to study. In this research, polymer concrete was developed by mixing orthophthalic unsaturated polyester resin, artificial ...
