Special flame-retardant asphalt for tunnels and preparation method thereof
The invention relates to the technical field of production of flame-retardant asphalt, and discloses special flame-retardant asphalt for tunnels and a preparation method thereof. The special flame-retardant asphalt comprises the following components in parts by weight: 30-45 parts of asphalt, 20-30 parts of coarse and fine aggregates, 5-15 parts of a flame-retardant modifier, 10-20 parts of mineral powder, 10-15 parts of waste residue powder, 2-5 parts of a stabilizer, 2-8 parts of hydrotalcite and 1-3 parts of a dispersant. According to the invention, the FRMAXTM flame-retardant modifier is used for modification production of asphalt, so the flame-retardant modifier has good dispersibility, safety and environmental protection performance in asphalt mixing and causes little pollution to the working environment, and the precipitation problem of a flame retardant in asphalt and the influence on asphalt performance indexes are fundamentally solved. The flame-retardant asphalt provided bythe invention not only has strong flame retardance, but also has good smoke suppression performance, low temperature resistance and durability, and the problem of cracking or weathering cracking of anasphalt pavement in a long-term use process is solved.
本发明涉及阻燃沥青生产技术领域，公开了一种隧道专用阻燃沥青及其制备方法，该阻燃沥青按重量份组分为：沥青30‑45份、粗细集料20‑30份、阻燃改性剂5‑15份、矿粉10‑20份、废渣粉10‑15份、稳定剂2‑5份、水滑石2‑8份、分散剂1‑3份。本发明通过采用FRMAXTM阻燃改性剂对沥青进行改性生产，使得阻燃改性剂在沥青混合中，具有良好的分散性和安全环保性能，同时对工作环境的污染小，从根本上解决了阻燃剂在沥青中的沉淀问题和对沥青性能指标的影响，本发明的阻燃沥青不仅阻燃性能强，还具有良好的抑烟性、耐低温性能和耐久性，解决了长时间使用过程中，沥青路面发生开裂或风化龟裂的现象。
