| Abstract: | Waste tire rubber–soil mixtures feature low density, high energy dissipation, and low shear modulus, which are widely used in geotechnical engineering for vibration attenuation. In this study, the evolution of the small-strain stiffness characteristics of clay-rubber mixture (CRM) is investigated; a resonance column test was carried out to determine the small-strain stiffness characteristics of CRM samples with different confining pressures ( σ 3 ), rubber particle contents ( C rubber ), and rubber particle sizes ( D rubber ). The test results indicate that σ 3 can promote the dynamic shear modulus (G) of CRM and restrain the damping ratio (D). The rubber particles have a great influence on both G and D. Under the same conditions, G decreases significantly with the increase in C rubber and increases slightly with the increase in D rubber , which indicates that rubber particles inhibit the development of G. D increases with the increase in C rubber and D rubber . The results show that the contact area between clay particles and rubber particles increases with the increase in C rubber , resulting in the decreases in G and D. The G–γ curves are analyzed by using the Hardin–Drnevich equation. Based on the fitting results, the maximum dynamic shear modulus ( G max ) is obtained. Therefore, the evolution of G max with σ 3 , C rubber , and D rubber are analyzed, and an equation for the G max of CRM considering the effects of σ 3 , C rubber , and D rubber is proposed. In addition, the D–γ curves can be well described by an empirical equation. [ABSTRACT FROM AUTHOR] |
