Abstract:The current society attaches great importance to environmental protection engineering, and highway pavement engineering is also no exception. In order to explore the influence and effect of warm-mixed agent on the modified asphalt and mixture, through the laboratory test analysis, the results shows that the warm-mixed asphalt becomes more stable because of its production principle and process, and has the advantages of lower energy consumption, lower cost, etc. The addition of RH warm agent has a relatively obvious improvement on the temperature of modified asphalt, which indicates that RH warm agent has a good cooling effect. The larger the dosage of RH warm agent is, the greater the amount of temperature change is. The addition of RH warm agent will not reduce the rutting performances of asphalt pavement, which belongs to the modified agent with no effect on pavement performance.
