Abstract
To study the properties of warm mix flame retardant asphalt mixture, a series tests were put forward, including Marshall Combustion experiments, rut specimen combustion experiment and texture depth experiment. With less mass loss, the warm mix retardant asphalt mixture has a better Marshall Stability, residual stability and freeze-thaw splitting strength ratio after combustion. The composite flame retardant can slow down and stop the burning of asphalt, reduce asphalt aging degree during burning process. The burning amount of warm mix flame retardant asphalt mixture is less than the ordinary hot mix asphalt concrete. To sum up, the warm mix flame retardant asphalt mixture has a good comprehensive performance.
