Bitumen stabilized ballast: a potential solution for railway track-bed
D'Angelo, Giacomo and Thom, Nicholas and Lo Presti, Davide (2016) Bitumen stabilized ballast: a potential solution for railway track-bed. Construction and Building Materials, 124 . pp. 118-126. ISSN 1879-0526
Railway ballast degradation under dynamic loads progressively leads to loss of mechanical performance and geometry of the track, so that maintenance interventions are frequently needed. In order to systematically avoid this issue, recently solutions have been proposed to reinforce track-bed by using polyurethane and/or resins as well as asphalt layers among others. Nonetheless, their main limitations are related to the high initial cost and low productivity.
