It can be observed from Figure 9 that compared to WMRA, the VTS of WMFRA blended with flame retardant showed a decreasing trend, indicating that the flame retardant can reduce the temperature sensitivity of asphalt, and the ZK flame retardant was the most effective in reducing the temperature sensitivity of WMFRA, which was reduced by 12.6%.
