Research on the Change of Ability of Warm Mix Flame Retardant Bitumen Based on Performance Comparison
Currently,China has the longest mileage of highway tunnel in the world,with the development of technology,in order to improve the safety and construction quality,domestic tunnel pavement construction gradually adopted warm flame retardant asphalt mixture.In this paper,based on the support project,the properties of the warm mix flame retardant asphalt mortar and the original asphalt are compared and analyzed from the aspects of high temperature performance,low temperature performance,aging performance and temperature sensitivity,and the asphalt mixture performance analysis is carried out based on the mix ratio design.The results show that the performance of the warm mix flame retardant asphalt mortar can be improved to a certain extent by adding the compound warm mix flame retardant agent.The properties of the warm mix flame-retardant asphalt mixture obtained by mixing are not lower than those of hot mix asphalt mixture.
