Abstract: To investigate the effect of rubber particle on the energy dissipation characteristics and damage evolution of cement soil (CS) under cyclic loading, graded cyclic loading-unloading tests were conducted on rubberized cement soil (RCS). By integrating digital image correlation (DIC) technology, the effects of rubber content and particle size on the stress-strain behavior, energy density, damage variable (D), damping ratio, and strain field of CS were analyzed. Results indicated that as the cycles number increased, the stress-strain curve of the RCS specimen exhibited a transition from sparse to dense characteristics. In the ranges of 20%, 40%, and 60% stress amplitude, both the input energy (U_I) and dissipated energy (U_D) displayed a two-stage attenuation characteristic, characterized by an initial steep decrease followed by a progressive decline as the cycles number increased. Conversely, at an 80% stress amplitude, the evolution of energy demonstrates a slow attenuation pattern. The incorporation of rubber particles effectively dissipated a portion of the energy through elastic deformation. This mechanism mitigates structural damage during cyclic loading-unloading, resulting in a reduction of D by 27% to 45% when compared to the CS specimen. The damping ratio increased with rubber content, while specimen with 0.1 mm rubber particles demonstrated superior damping performance at a given dosage. An increase in rubber content was accompanied by a transition in the failure mode of specimen from brittle to ductile, characterized by multiple cracks, and a significant enhancement in transverse deformation ability.
