“…Sun Indraratna [12] found that the high compressive load-bearing capacity of TESEs can be theoretically explained by the increased apparent cohesion due to the additional confining forces of the encasement tyre when the TESEs are subject to compressive loadings. TESEs have been used in constructing low-rise buildings, railway foundations, reinforced slopes, retaining walls, and embankments [2,5,9,12,13,[17][18][19][20][21]. Reusing EOL tyres as reinforcement materials in engineering structures is an attractive solution to reducing the volume of used tyres disposed into landfills [9], with the added potential benefit of reduced cost for reinforced earth structure construction [2].…”

The reuse of end-of-life (EOL) tyres as earth reinforcement materials in civil engineering projects have been studied for decades. Entire EOL tyres infilled with compacted soil can form segmental tyre encased soil elements (TESEs) with considerable load-bearing capacity. The TESEs can be used to construct structures like low-rise buildings, railway foundations and geotechnical structures. One of the most important aspects of TESE systems, i.e., the shearing interaction between neighbouring units is not yet well understood. In this study, thirty-six laboratory tests have been conducted to investigate the response of TESEs under intercourse shear actions. This was followed by a supply chain environment and economic analysis to investigate the acceptability of the system. The results revealed that the type of encased soil had more effect on the interface interactions between courses of TESEs compared to the TESEs’ construction pattern. It was also found that the frictional coefficient could be increased by either using coarse and angular aggregates as the encased soil or reducing the amount of the encased soil to form a high portion of rubber-to-rubber contact at the composite interface. Supply chain environment and economic analysis revealed that using entire tyres as construction materials has low CO2 emission and considerable economic benefits.
