Flame-retardant warm-mixed modified asphalt as well as preparation method and application thereof
The invention discloses flame-retardant warm-mixed modified asphalt as well as a preparation method and application thereof. The flame-retardant warm-mixed modified asphalt comprises the following components in parts by mass: 100 parts of modified asphalt; 2-4 parts of a warm mixing agent; and 10-15 parts of a flame retardant. The flame retardant comprises antimony oxychloride and antimony trioxide in a mass ratio of 10:(1-4); and the warm mixing agent comprises a Sasobit warm mixing agent. According to the flame-retardant warm-mix modified asphalt disclosed by the invention, the warm-mix performance of the asphalt is improved through the Sasobit warm-mix agent, and the Sasobit warm-mix agent is matched with the flame retardant disclosed by the invention, so that the oxygen index of the asphalt can be synergistically improved, the ignition time of the asphalt can be prolonged, and the combustion heat release rate and the CO release rate of the asphalt can be reduced.
本发明公开了一种阻燃温拌改性沥青及其制备方法和应用，按质量份，改性沥青100份；温拌剂2‑4份；阻燃剂10‑15份；其中，所述阻燃剂包括质量比为10：(1‑4)的氯氧化锑和三氧化二锑；所述温拌剂包括Sasobit温拌剂。本发明的阻燃温拌改性沥青，通过Sasobit温拌剂在提高沥青的温拌性能的同时，与本发明的阻燃剂搭配，可以协同提高沥青的氧指数，延长沥青点燃时间，降低沥青燃烧热释放速率和CO释放率。
