Abstract: Rubber modified asphalt enables the reuse of waste materials and promotes environmental protection, while effectively enhancing the road performance of materials. However, it also presents challenges in terms of high energy consumption and pollution. Warm mixing agent offers a viable solution to address these issues by significantly improving various aspects of rubber asphalt. In this study, three warm mixing agents with distinct action mechanisms were selected to investigate their effects on the properties of 30% rubber modified asphalt. The warm mixing agent exhibits minimal impact on the structural integrity of rubberized asphalt, maintaining its performance stability. The warm mixing agent exhibits a beneficial effect on the alteration of rubberized asphalt elongation post-aging, with EC120 displaying the most pronounced propensity to retard asphalt aging. However, the viscosity of rubber asphalt fortified with EC120 warm mixing agent demonstrated a rapid increase when exposed to high temperatures.
