- Random fibre reinforcement of railway ballast can improve strength and ductility, and reduce the ongoing settlement that necessitates expensive maintenance interventions. Based on triaxial tests on scaled materials, the paper develops a behavioural framework that accounts for the additional effective confining stress in the granular matrix resulting from fibre tensions. The approach could increase the time interval between maintenance tamping by a factor of 2-5, and field trials are now in progress on London Underground. The paper was awarded the British Geotechnical Association Medal 2018 and led to an invited keynote lecture at the GeoMEast conference 2018.
