Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms
Fonseca, J., Riaz, A., Bernal-Sanchez, J., Barreto Gonzalez, D., McDougall, J., Miranda Manzanares, M., …Dimitriadi, V. (2019)
Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms. Géotechnique Letters, 9(4), 1-6. https://doi.org/10.1680/jgele.18.00221
Sand-rubber mixture (SRm) behaviour is affected by rubber content (RC) whilst dissipation in sands is caused by inter-particle sliding. Dissipation in SRm is as, or more signi...

Presentation / Conference
Kelly, D., McDougall, J., & Barreto, D. (2012, August)
Effect of particle loss on soil behaviour. Paper presented at ICSE-6 6th International Conference on Scour and Erosion
Soil particle loss can result in strength and volume reductions which are difficult to predict. This paper investigates the
influence of the removal of fractions of selected p...
