Abstract: In this paper, the road performance and application effect of warm mix flame retardant asphalt mixture are studied by laboratory test and engineering application. Research shows that: the mixing of BFRTi flame retardant and Evotherm warm mix has little influence on the road performance of asphalt mixture, and the performance indexes are in the standard range. The engineering example shows that the warm mix asphalt mixture has good road performance, and the effect is very good, and the application prospect is broad.
