“…Thus, in such conditions, the locally available clayey soils can be considered as the alternative backfills. Usually, the geotechnical characteristics of these clays are improved by using the additives, and the compaction is the fundamental technique to densify these stabilized materials during in situ placement [3,[8][9][10][11].…”

Artificial compaction is a commonly practiced ground improvement technique around the world. Yield stress is an important parameter to quantify and analyze the strength and compressibility behavior of the artificially compacted clays; such materials are indeed of practical significance in various projects, e.g., engineered landfills, clay liners, etc. The present study aims to investigate the influence of different geotechnical characteristics of compacted clays of wide plasticity range on the compaction induced yield stress, and also to develop the correlational models to quickly predict the yield stress. Three natural clayey soil samples of different geotechnical properties were collected from different sites; 27 more samples of varying index properties were prepared by mixing bentonite with natural soil samples at varying rates. Series of one-dimensional consolidation tests were performed to determine compressibility parameters like yield stress, compression index, and coefficient of volume compressibility. Atterberg's limits, grain size, compaction characteristics, and compressibility have a significant influence on the compaction induced yield stress. Predictive models of yield stress are also developed by using the plasticity index, optimum water content, and maximum dry unit weight as independent variables. Moreover, developed models are validated based on the independent data.

“…However, at the optimum water content and towards dryer soil, there are many theories to explain why soil bulk density reaches a maximum, and after that, decreases. Pértile, Reichert, Gubiani, Holthusen, and Costa (2016) and Kodikara, Islam, and Sounthararajah (2018) argue that under the application of compaction energy, the ranged bulk density should be lower for dry soil because of high capillarity force (i.e. high soil water tension) that strengthens particle bonds and hence increases soil strength.…”

In this work, we aimed to investigate changes in compressive properties and least limiting water range (LLWR) of the plough layer and plough pan induced by successive years of sugarcane cultivation. Undisturbed soil samples were collected in a sugarcane field at the plough layer and below tillage depth (plough pan). Uniaxial compression tests were performed for a water tension (h) range of 30 to 15,000 hPa for calculations of the compressive parameters N (the specific volume at 1 kPa), λ (compression index) and κ (recompression index), besides the precompression stress (σ p ). The LLWR was examined through the water retention and penetration resistance curves. σ p linearly increased with the increase in the compaction state (plough pan) and h, whereas κ decreased with the increase in the h with no significant effect of compaction level. N and λ presented peaks at intermediate h values (100-2,000 hPa).Considerable reductions in the LLWR were observed from the plough to plough pan layer, which was induced by the increase in the soil penetration resistance. These results suggest that the residual plough pan induced by the successive years of intensive use of machinery for field operations in sugarcane areas originates a soil layer of lower compressibility and higher strength that further increases as the soil dries in response to h. Moreover, the consequent increase in the soil penetration resistance from the plough to plough pan is the main factor negatively affecting the LLWR.

“…Rock and soil material to be disposed of in landfill are subject to minimum requirements regarding compaction, load-bearing capacity and suitability for incorporation in the landfill body. Compaction has a direct impact on the load-bearing capacity, both in terms of static and dynamic loads, and on the stability of the structure [4,5]. The excavated material generated during tunnelling is not a homogenous 'standard grain mixture' in terms of its geometric, physical and chemical characteristics and may vary substantially as the tunnel advances.…”

Large quantities of excavated rocks are generated during tunnel driving. Recycling possibilities and total percentage of recycling are depending on the rock conditions (rock type and rock properties), as well as the applied driving method. If recycling of the excavated rock mass is not possible or reasonable from a technical or economical point of view, the excavated material needs to be deposited in landfills. Thereby, the consumed landfill volume depends on the material volume of non‐recyclable rock and its compactability as a function of the loosening of the rock by excavation and landfill installation. Both, material volume and compactability of the excavated material, are difficult to evaluate in advance. Apart from unpredictable lithological changes and variation of the driving parameters (e.g. depth of advance in conventional driving, contact pressure of tunnel boring machine), external influences – like afflux of water or weather conditions during installation of the material – significantly affect the compactability of the excavated aggregates. In this study, the actual example of phyllitic rock material excavated by conventional drilling and blasting from the main tunnel tubes of the Brenner Base Tunnel has been chosen to take a closer look at the research question concerning the compactability of phyllitic rock material. Since excavation material is increasingly used in construction industry, detailed knowledge on this matter is necessary for a successful application.
