Laboratory testing of a mass of large particle sized Tire Derived Aggregate (TDA) to assess performance related properties such as void ratio, compressive creep and hydraulic conductivity under large loads poses a number of experimental challenges. L... Read More about 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 (2018)
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 restoring the former landfill space. The success of the process depends on... Read More about Estimating degradation-related settlement in two landfill-reclaimed soils by sand-salt analogues.

Experimental Assessment and Modelling of Coupled Biochemical-Physical-Mechanical Biodegradation Process of a Municipal Solid Waste Sample from Michigan (2017)
Presentation / Conference Contribution
Datta, S., Zekkos, D., Fei, X., & McDougall, J. (2017). Experimental Assessment and Modelling of Coupled Biochemical-Physical-Mechanical Biodegradation Process of a Municipal Solid Waste Sample from Michigan. In Proceedings of the 2nd Symposium on Couple

Municipal solid waste (MSW) is biodegradable in landfills under anaerobic conditions. The evolution of the biochemical, physical and mechanical characteristics of MSW are interdependent and is investigated first through an experiment and subsequently...

Review and application of a settlement model for landfills (2017)
Presentation / Conference Contribution
Esteban-Altabella, J., McDougall, J., Colomer-Mendoza, F., Gallardo, A., & Edo-Alcon, N. (2017, October). Review and application of a settlement model for landfills. Presented at 16TH International Waste Management and Landfill Symposium Sardinia 2017

The geotechnical behavior and settlement in landfills has been changing for many years. This behavior in fact depends on many factors and, therefore, making forecasts is complicated due to the effect of biodegradation. In order to solve this issue, m...

Design of geotechnical systems is often challenging as it requires the understanding of complex soil behaviour and its influence on field-scale performance of geo-structures. To advance the scientific knowledge and the technological development in ge...

Results from two sets of laboratory test programmes on sand-salt mixtures in wihch the salt fractions, of different amounts and size, are dissolved are brought together to gather insight into the mechanics of mass loss and its controlling factors. Th... Read More about Mass loss and volume change: From sand-salt analogues to MSW.

Volumetric consequences of particle loss by grading entropy (2013)
Journal Article

Chemical and biological processes, such as dissolution in gypsiferous sands and biodegradation in waste refuse, result in mass or particle loss, which in turn lead to changes in solid and void phase volumes and grading. Data on phase volume and gradi... Read More about Volumetric consequences of particle loss by grading entropy.

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 composition and grading. In this paper, the influence of size and amount of par... Read More about Particle loss and volume change on dissolution: experimental results and analysis of particle size and amount effects.

Effect of particle loss on soil behaviour. (2012)
Presentation / Conference Contribution
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 particle sizes under different confining pressures. The mass loss process...

Settlement-The Short and the Long of it (2011)

Total settlement in municipal solid waste (MSW) landfills can be considerable, from 25% to 50% of original fill thickness (Bjarngard and Edgers, 1990). Some occurs very quickly, i.e. during the filling phase (or short term), but there remains a signi... Read More about Settlement-The Short and the Long of it.
