Physical and Mechanical Properties of Granulated Rubber Mixed with Granular Soils—A Literature Review

End-of-life tires (ELTs) represent a great source of readily available, low-cost and sustainable construction materials having excellent engineering properties. Their reuse (in the form granulated rubber mixed with soils) in large-volume recycling civil (geotechnical) applications would be beneficial should encouraged. It is estimated that at present worldwide only less than 10% ELTs are reused geotechnical applications, while nearly 40% recycled as tire-derived fuel. Although many studies have focused on material characterization soil-rubber mixtures (SRMs), it appears results such investigations not been properly compiled compared, making difficult to fully understand potential applicability SRMs. In an attempt provide useful insights facilitating use SRMs materials, this review paper presents comprehensive published research properties granular soils (i.e., mainly sand gravel) blended various inclusions. Available experimental data scrutinized, analyses presented discussed primarily terms effects content aspect ratio (ratio gravel median particle sizes) compaction, permeability, strength compression along dynamic cyclic deformation characteristics This may help alleviate concerns designers consumers encourage further promote larger scale projects.
