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...

Quantifying Particle Breakage and Its Evolution Using Breakage Indices and Grading Entropy Coordinates (2022)
Journal Article
Leak, J., Barreto, D., Dimitriadi, V., & Imre, E. (2022). Quantifying Particle Breakage and Its Evolution Using Breakage Indices and Grading Entropy Coordinates. Geotechnics, 2(4), 1109-1126. https://doi.org/10.3390/geotechnics2040052

Particle breakage in soils is a well-recognised behaviour. Conventional methods for quantifying the breakage process rely on calculating the area between the particle size distribution (PSD) curves produced before and after crushing. A key aspect of...

Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection (2022)
Presentation / Conference Contribution
Bernal-Sanchez, J., McDougall, J., Miranda-Manzanares, M., & Barreto, D. (2022, September). Dynamic Behaviour of a Geotechnical Seismic Isolation System with Rubber-Sand Mixtures to Enhance Seismic Protection. Presented at 3rd European Conference on Earth

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.

The permeability variables of granular matter (2022)
Presentation / Conference Contribution
Imre, E., Illes, Z., Balint, A., Gonzales, H., Repassy, L., Quynh Huong, D. T., …Singh, V. P. (2022). The permeability variables of granular matter. In VIth International Symposium-2022 on “Biosphere & Environmental Safety” Proceedings Book (201-2

No “unique” relation between soil parameters and grading curves of granular matter can be elaborated. In case some statistics are used (e.g., d10), then infinite many grading curves may be related to the same value of it. Moreover, several densities...

Recent Advances in Nature-Inspired Solutions for Ground Engineering (NiSE) (2021)
Journal Article
Assadi-Langroudi, A., O’Kelly, B. C., Barreto, D., Cotecchia, F., Dicks, H., Ekinci, A., …van Paassen, L. (2022). Recent Advances in Nature-Inspired Solutions for Ground Engineering (NiSE). International Journal of Geosynthetics and Ground Engineering

The ground is a natural grand system; it is composed of myriad constituents that aggregate to form several geologic and biogenic systems. These systems operate independently and interplay harmoniously via important networked structures over multiple...

Some Notes on Granular Mixtures with Finite, Discrete Fractal Distribution (2021)
Journal Article
Imre, E., Talata, I., Barreto, D., Datcheva, M., Baille, W., Georgiev, I., …Lőrincz, J. (2022). Some Notes on Granular Mixtures with Finite, Discrete Fractal Distribution. Periodica Polytechnica Civil Engineering, 66(1), 179-192. https://doi.org/10.331

Why fractal distribution is so frequent? It is true that fractal dimension is always less than 3? Why fractal dimension of 2.5 to 2.9 seems to be steady-state or stable? Why the fractal distributions are the limit distributions of the degradation pat... Read More about Some Notes on Granular Mixtures with Finite, Discrete Fractal Distribution.

In a previous research program 74 artificial soil mixtures of natural fluvial soils were prepared in 4 series of measurements for falling head permeability testing, differing in d 10. The conclusions drawn from the original investigations were as fol... Read More about Examination of saturated hydraulic conductivity using grading curve functions.
