Study on Properties of Flame Retardant Asphalt for Tunnel

摘要

The flame flame-retardant asphalt for a tunnel containing various kinds of flame retardants including decabromodiphenyl oxide (DBDPO), decabromodiphenyl ethane (DBDPE), Sb_2O_3, ZnBO_3, Mg(OH)_2, and Al(OH)_3 under different additive concentrations was studied. To improve the properties of asphalt changed by adding the flame retardants, a smoking inhibitor and blender were used and the effect on the properties was investigated. Finally, the styrene butadiene rubber (SBR) modifier was added to the asphalt in order to increase the ductility. Asphalt with both good flame retardancy retardance and paving properties was prepared successfully to meet two demands as flame-retardant materials and road materials at the same time.
