Effect of Organic Warm Mixing Agent on Performance of High-viscosity Asphalt Mixture
This paper analyzed the change in mechanical properties,road performance,and construction performance of the high-viscosity asphalt mixtures after adding the organic warm mixing agent.The results showed that the adhesion and the maximum flexural strain could be used as the control index of the content of the organic warm mixing agent,and the organic warm mixing agent could solve the problems of high construction temperature and difficulty in the mixing of high-viscosity asphalt mixture.Through the analysis of the comprehensive properties of the material,it was concluded that the high-temperature and compressive properties could be further improved to be applied to the middle and lower layer of the road with small temperature variations or heavy traffic.
