摘要

As the automobile industry expands, the waste tires are stockpiling worldwide in every nation and become an objectionable urban waste. One potential substitute to prevent such stockpiling in the environment by combining rubber with sand particles to create lightweight backfill. The use of waste tires for civil engineering applications has been widely studied and proven a valuable source of sustainable, abundant cheap building materials with good mechanical properties. So if they could be reused widely as alternative geomaterial then such application should be promoted. Currently, less than 10% of the nearly one billion ELTs generated yearly worldwide are recovered in geotechnical end-use application and approximately 40% is turned into tire-derived fuel. While considerable work has been dedicated to the material characterization of soil-rubber mixtures (SRMs), these datasets have not, as yet, aggregated and compared in a comprehensive way which could underscore the potential adaptation rates for SRMs. This review intended to offer practical insights about the use of soil-rubber mixtures as an alternative of conventional geomaterial. The present work includes the review of different methodology followed for the sample preparation in the experimental investigation. Additionally, the methodology adopted in the literature during physical modeling for application of static loading to determine deformation characteristics, load-bearing phenomenon in granular soil mixed with waste tire rubber has been discussed in detail in the present paper. The detailed review shows how the rubber content enhances the durability and reduces the density of the soil, leading to potential applications where reduced weight and increased flexibility are beneficial.
