Flame-retardant warm-mixing self-healing asphalt concrete as well as preparation method and application thereof
The invention discloses flame-retardant warm-mixing self-healing asphalt concrete as well as a preparation method and application thereof, and the flame-retardant warm-mixing self-healing asphalt concrete comprises the following components in parts by mass: 100 parts of modified asphalt; 4-8 parts of a warm mixing agent; 4-10 parts of a flame retardant; 6-13 parts of a self-healing component; 1800-2200 parts of an aggregate; and 170-230 parts of mineral powder. The self-healing component is a self-healing microcapsule and/or steel wool fiber, and the warm mixing agent is artificial zeolite. Compared with the prior art, the flame-retardant warm-mixing self-healing asphalt concrete has the advantages that the warm-mixing performance of the asphalt concrete is improved through the artificial zeolite, and the artificial zeolite is matched with the flame retardant, so that the oxygen index of the asphalt concrete can be synergistically improved, the ignition time of the asphalt concrete can be prolonged, and the combustion heat release rate and the CO release rate of the asphalt concrete can be reduced.
本发明公开了一种阻燃温拌自愈合沥青混凝土及其制备方法和应用，按质量份，包括以下组分：改性沥青100份；温拌剂4‑8份；阻燃剂4‑10份；自愈合成分6‑13份；集料1800‑2200份；矿粉170‑230份；其中，所述自愈合成分为自愈合微胶囊和/或钢棉纤维，所述温拌剂为人造沸石。与现有技术相比，本发明的阻燃温拌自愈合沥青混凝土，通过人造沸石在提高沥青混凝土的温拌性能的同时，与本发明的阻燃剂搭配，可以协同提高沥青混凝土的氧指数，延长沥青混凝土点燃时间，降低沥青混凝土燃烧热释放速率和CO释放率。
