Laboratory Evaluation of Pavement Performance and Burning Behavior of Flame-Retardant Asphalt Mixtures

This study evaluated the effect of flame retardant on the pavement performance and burning properties of asphalt mixtures. Two flame-retardant additives (homemade and commercial) were separately added to control asphalt mixtures. Moisture-susceptibility, rutting, and low-temperature cracking tests were conducted to determine the pavement performance of these mixtures. In addition, the burning properties of these mixtures were evaluated through intuitive observation, burning-duration time, surface temperature, and residual stability after burning. From the pavement performance test results, the flame-retardant asphalt mixture showed decreased moisture susceptibility, better performance of resistance to rutting, and no change in the low-temperature cracking when compared to the control asphalt mixture. In addition, the flame-retardant asphalt mixture was effective in delaying the flame time and decreasing the surface temperature and residual stability after burning.
