The waste tire rubber may be incorporated with the cement soil to improve its frost resistance. However, it remains a significant challenge optimise content between mechanical strength and durability under freeze-thaw conditions. In this study, macroscopic properties of ordinary rubber-cement (with particle sizes 30 60 mesh) were explored different cycles (0, 3, 6, 9, 15) by taking wave propagation unconfined compressive (UCS) tests. Subsequently, series scanning electron microscope (SEM) X-ray diffraction (XRD) tests conducted analyse microstructure specimens, further clarifying damage mechanisms in soil. results show that cause irreversible internal soil, leading continuous reductions both velocity UCS. After 15 cycles, loss rates are 95%, 72.2%, 89.7% for mixed 30-mesh 60-mesh particles, respectively. corresponding UCS 95.4%, 82.7%, 89.2%, above suggest exhibits superior From microstructural perspective, particles delay inhibit heaving cracks, forming denser spatial structure calcium silicate hydrates (C-S-H) gel, thereby improving By integrating testing analysis, study reveals mechanism conditions, providing valuable insights engineering applications.
