“…The literature on tyre reinforcement has shown that the ultimate pull-out capacity of a waste tyre is 1.25 times that of a geocell or similar reinforcing material (Kim et al, 2011). In addition, the effect of reinforcement has also been found to be significant when applied to a sand foundation (Yoon et al, 2004(Yoon et al, , 2008.…”

a b s t r a c tTyre-reinforced soil, used to improve slope stability, retaining walls, etc., has an excellent mechanical performance, and has the capability of a wider application and of reducing waste disposal costs. This article studies the stress and deformation characteristics, as well as the influencing factors related to the reinforcing arrangement, through small scale model embankment tests. It is shown that tyre reinforcement highly improved the strength of the model embankments; much higher stresses were mobilised inside the soil mass (around 2 times higher in comparison with the unreinforced embankment). There is an obvious plastic flow in the unreinforced embankment, while the plastic zone, on the reinforced embankments, was difficult to determine. Comparisons between the vertical settlement of the embankments show that the settlement of the reinforced embankment is roughly half of the settlement of the unreinforced embankment, for the same vertical load applied. These results also show that the tests with the top layer of reinforcement nearer the load application area and a smaller distance between the intermediate layers have a better performance, particularly in dense fabrics. The location of the top reinforcement layer seems to dominate the failure modes of the reinforced and unreinforced embankments, the horizontal deformations and the location of the shear bands in the embankment.

“…Another form of use has been as a ground reinforcement, either with the whole tires or strips [26][27][28][29][30][31]. In recent studies [30], researchers discussed the benefits of reinforcing dikes and embankments with the whole tire by running a series of field-level pullout tests to investigate the behavior of waste tire extraction in cell-type arrangements on reinforced soil.…”

The tires used constitute an environmental problem that remains unsolved. It is observed that the automotive fleet and therefore the generation of tires increases year after year, so the recovery and reuse processes are insufficient. For several years, the reuse of tires as materials in the construction has been considered, and several techniques have been developed for the construction of retaining walls and road reinforcement. However, to date, their use remains sporadic. This article presents the theoretical and experimental evaluation of a new geotechnical reinforcement system from used tires. This system, suitable for the construction of containment structures and the reinforcement of roads, is characterized by the conformation of cells that do not require other elements apart from the tires and the filling material. A mathematical model was developed to describe the behavior of the system and pullout tests were carried out for validation. The tests were performed with different tire and compacted granular material with different energies. The results allow validating the theoretical model by showing an increase in pullout resistance with the density and number of tires in the arrangement. It is observed that the coincidence between the model and the tests improves as the stiffness of the soil increases, being the degree of compaction fundamental for the operation.

“…The authors of [ 18 ] have shown the benefits of reinforcing dikes and embankments with whole tires, whilst [ 19 , 20 ] found that with the addition of tire shreds, the shear strength properties of the reinforced soil were higher than the properties of the unreinforced soil. If waste tire particles are added to a clayey soil and mixed with cement, the performance of the cement admixed soil can be significantly improved [ 21 ]. They carried out a series of field-scale pull-out tests to investigate the pull-out behavior of cell-type waste tires in reinforced soil.…”

Waste tires have excellent mechanical performance and have been used as reinforcing material in geotechnical engineering; however, their interface properties are poorly understood. To further our knowledge, this paper examines the pull-out characteristics of waste tire strips in a compacted sand, together with uniaxial and biaxial geogrids also tested under the same conditions. The analysis of the results shows that the interlocking effect and pull-out resistance between the tire strip and the sand is very strong and significantly higher than that of the geogrids. In the early stages of the pull-out test, the resistance is mainly provided by the front portion of the embedded tire strips, as the pull-out test continues, more and more of the areas towards the end of the tire strips are mobilized, showing a progressive failure mechanism. The deformations are proportional to the frictional resistance between the tire-sand interface, and increase as the normal stresses increase. Tire strips of different wear intensities were tested and presented different pull-out resistances; however, the pull-out resistance mobilization patterns were generally similar. The pull-out resistance values obtained show that rubber reinforcement can provide much higher pull-out forces than the geogrid reinforcements tested here, showing that waste tires are an excellent alternative as a reinforcing system, regardless of the environmental advantages.
