Numerical modeling of coupled biochemical and thermal behavior of municipal solid waste in landfills

Journal Article
Kumar, G., Reddy, K. R., & McDougall, J. (2020)
Numerical modeling of coupled biochemical and thermal behavior of municipal solid waste in landfills. Computers and Geotechnics, 128, https://doi.org/10.1016/j.compgeo.2020.103836
A coupled bio-thermal (BT) model is proposed and validated for the prediction of long-term biochemical and thermal behavior of municipal solid waste (MSW) in landfills. The bi...

Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms

Journal Article
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...

Particle loss: An initial investigation into size effects and stress-dilatancy

Journal Article
McDougall, J., Kelly, D., & Daniel, B. (2019)
Particle loss: An initial investigation into size effects and stress-dilatancy. Soils and Foundations, https://doi.org/10.1016/j.sandf.2019.03.002
Drained triaxial tests have been performed to explore the effect of particle loss on shearing behaviour and critical states in granular mixtures. The mixtures comprise Leighto...

Waste-composition-dependent HBM model parameters based on degradation experiments

Journal Article
Datta, S., Zekkos, D., Fei, X., & McDougall, J. (2021)
Waste-composition-dependent HBM model parameters based on degradation experiments. Environmental Geotechnics, 8(2), 124-133. https://doi.org/10.1680/jenge.18.00014
Municipal solid waste (MSW) is biodegradable in landfills under anaerobic conditions. The evolution of the hydro-biochemical-mechanical (HBM) processes during degradation is ...

Strategies for One Dimensional (1D) Compression Testing of Large-Particle-Sized Tire Derived Aggregate

Estimating degradation-related settlement in two landfill-reclaimed soils by sand-salt analogues

Journal Article
McDougall, J., Fleming, I., Thiel, R., Dewaele, P., Parker, D., & Kelly, D. (2018)
Estimating degradation-related settlement in two landfill-reclaimed soils by sand-salt analogues. Waste Management, https://doi.org/10.1016/j.wasman.2018.04.013
Landfill reclaimed soil here refers to largely degraded materials excavated from old landfill sites, which after processing can be reinstated as more competent fill, thereby r...

Particle loss and volume change on dissolution: experimental results and analysis of particle size and amount effects

Journal Article
McDougall, J., Kelly, D., & Barreto, D. (2013)
Particle loss and volume change on dissolution: experimental results and analysis of particle size and amount effects. Acta geotechnica, 8(6), 619-627. https://doi.org/10.1007/s11440-013-0212-0
Soil particles may be lost through dissolution, degradation or erosion. Regardless of the process of loss, there follows a change in soil structure both in terms of phase comp...
