“…The formed mixtures outperform the soils in respect to resilience, strength, ductility and damping [5][6][7]. The demonstrated advantages arises from the rubber material's capacity of increasing inter-particle interactions which were confirmed in triaxial [3,5,[8][9], direct shear [10][11][12][13] and uniaxial pull-out tests [14].…”

“…On the other hand, geotechnical applications need high volume of soils which helps consuming a large quantity of wastes [15]. Balunaini et al [2] reported that rubber waste can be used in several civil engineering applications such as embankment fill material, drainage material, vibration dampening material underneath railways, thermal insulation layer and asphalt rubber paving layer. In addition, rubber wastes were used as fine and coarse aggregates in concrete material as reported in several investigations [7,9,13,18,21].…”

In this study, an alternative and environmentally friendly method for the reinforcement of dune sand is proposed. This technique consists of using randomly distributed rubber fibers to improve the engineering properties of sand. Rubber fibers are added to the sand with different percentages: 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75 and 2% of dry weight of sand. The experimental program carried out consists of investigating the effect of rubber fibers on the shear strength properties of sand. Reinforced and unreinforced samples are tested in the dense as well as loose state. The results obtained showed that the inclusion of rubber fibers in dune sand will improve the engineering properties of various civil engineering applications such as shallow foundations and slope. Therefore, incorporation of rubber fibers can enhance the shear strength characteristics, peak and residual strengths, and introduce more ductility to the mechanical behavior of sand. In addition to the technical effect, this paper emphasizes another environmentally attractive option, which is the use of rubber fibers as reinforcements for granular soils as this helps to remove some parts of these wastes and protect the environment.

“…It is well known that the volumetric fraction of a mixture and its boundary conditions determine its physico-mechanical properties. In particular, rubber particles with low density, stiffness and conductivity can be mixed with soil to decrease its effective unit weight, to improve its thermal insulation and to modulate strain-dependent stiffness and other properties of interest, including the maximum shear stiffness damping, time-dependent settlement, thermal conductivity and shear strength [ 1 , 2 , 3 , 4 , 5 , 6 ]. Damping and creep strain, shear stiffness and thermal resistivity have been found to increase with an increasing fraction of crumb rubber.…”

Shredded rubber tire is a geomaterial that is potentially useful in environmental and engineering projects. Here, we study the effect of particle size ratio on the thermal conductivity of granular mixtures containing rubber tire particles. Glass beads were mixed at various volume fractions with rubber particles of varying size. The 3D network model analysis using synthetic packed assemblies was used to determine the dominant factors influencing the thermal conduction of the mixtures. Results present that mixtures with varying size ratios exhibit different nonlinear evolutions of thermal conductivity values with mixture fractions. In particular, mixtures with large insulating materials (e.g., rubber particles) have higher thermal conduction that those with small ones. This is because the larger insulating particles allow better interconnectivity among the conductive particles, thereby avoiding the interruption of the thermal conduction of the conductive particles. Similar tests conducted with natural sand corroborate the significant effect of the relative size of the insulating particles. The 3D network model identifies the heterogeneity of local and effective thermal conductivity and the influence of connectivity among conductive particles. A supplementary examination of electrical conductivity highlights the significance of local and long-range connectivity on conduction paths in granular mixtures.
