| Abstract: | Starting from the diffusion theory, the diffusion mechanism between rejuvenation agent and aged asphalt is analyzed. The temperature.the property of rejuvenation agent and property of asphalt are considered as three important factors which affect the diffusion ability of rejuvenation agent during asphalt hot recycling. Through simulation test on diffusion from aged asphalt to new aggregate, the mixing time, construction temperature, quantity of rejuvenation agent and quantity of aged asphalt which affect the diffusion and transference of aged asphalt binder are analyzed. |
