Chang (Eds.), Geo-Congress 2024: Soil Improvement, Sustainability, Geoenvironmental, and Cold Regions Engineering (714-724). https://doi.org/10.1061/9780784485330.072

Particle size distribution (PSD) is recognised among geotechnical engineers as an informative soil descriptor, and often used to predict geomechanical behaviours. However, the effectiveness of PSD to characterise frost action is debatable. Existing c... Read More about A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria.

Carbon impact & mitigation of housing developments on peatlands in the UK - A case study (2023)
Conference Proceeding
Bernal-Sanchez, J., & Gaspari, A. (2023). Carbon impact & mitigation of housing developments on peatlands in the UK - A case study. In Proceedings of the ISSMGE TC215 9th International Congress on Environmental Geotechnics 25-28 June 2023 (361-371). https://doi.org/10.53243/ICEG2023-216

Peatlands are a key asset in the drive to reduce annual carbon emissions due to their potential as a carbon sink. This is especially important in Scotland where 25% of the land is covered by peat. Peatlands have historically been considered wasteland... Read More about Carbon impact & mitigation of housing developments on peatlands in the UK - A case study.

Rubber-soil mixtures: use of grading entropy theory to evaluate stiffness and liquefaction susceptibility (2023)
Journal Article
Bernal-Sanchez, J., Barreto, D., & Leak, J. (2023). Rubber-soil mixtures: use of grading entropy theory to evaluate stiffness and liquefaction susceptibility. Bulletin of Earthquake Engineering, 21, 3777–3796. https://doi.org/10.1007/s10518-023-01673-3

Rubber-soil mixtures are known to have mechanical properties that enable their use in backfills, road construction or geotechnical seismic isolation systems. The complexity of these mixtures comes from adding soft (i.e. rubber) particles that increas...

Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection (2022)
Conference Proceeding
Bernal-Sanchez, J., McDougall, J., Miranda-Manzanares, M., & Barreto, D. (2022). Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection. In Proceedings of the 3rd European Conference on Earthquake Engineering & Seismology (2674-2683)

A Geotechnical Seismic Isolation (GSI) system is proposed in this study based on the use of Rubber-Soil mixtures (RSm) to facilitate the benefits of dynamic soil-foundation structure interaction. The latter is possible due to the lower stiffness and... Read More about Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection.

Housing Construction On Peatland: Phase 1 Report (2021)
Report
Bernal-Sanchez, J., McDougall, J., Medero, G., Cook, D., & Barreto, D. (2021). Housing Construction On Peatland: Phase 1 Report. Edinburgh: Construction Scotland Innovation Centre

The economic development and social resilience of communities in rural Scotland is being hampered by a shortage of affordable housing. Nationally, about 23,000 new homes per year are needed, whilst in the year up to October 2018, only 18,000 were bui... Read More about Housing Construction On Peatland: Phase 1 Report.

Cyclic performance of rubber-soil mixtures to enhance seismic protection (2020)
Thesis
Bernal Sanchez, J. Cyclic performance of rubber-soil mixtures to enhance seismic protection. (Thesis). Edinburgh Napier University. Retrieved from http://researchrepository.napier.ac.uk/Output/2683555

The disposal of scrap tyres has become a major environmental problem around the world. For its recovery, a geomaterial has been used as part of civil constructions, commonly known as Rubber-Soil mixture (RSm). The use of RSm has the potential to be u...

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 significant than in sands. However, the mechanisms of dissipation in SRm are not... Read More about Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms.
