一种阻尼多孔降噪隧道沥青面层材料的制备方法
摘要：
本发明涉及一种隧道沥青面层材料的制备方法。一种阻尼多孔降噪隧道沥青面层材料的制备方法，其特征在于它包括如下步骤：1)高粘度高弹性改性沥青的制备：按各组分的质量比为基质沥青∶改性剂SBS∶活化橡胶粉∶增粘增容剂∶抗氧剂∶稳定剂＝100∶6.0～18.3∶20.2～45.7∶1.2～3.7∶0.2～1.4∶0.4～1.9，选取；制得高粘度高弹性改性沥青；2)在高粘度高弹性改性沥青中加入阻燃剂，将高粘度高弹性改性沥青加热熔化添加阻燃剂，搅拌3～9min，150～170℃静置15～30min，即得阻燃高粘度高弹性改性沥青；3)按质量比为矿料∶阻燃高粘度高弹性改性沥青∶纤维稳定剂＝100∶3.6～5.2∶0.1～0.4，选取；制得阻尼多孔降噪隧道沥青面层材料。本发明具有降噪、阻燃、抗滑功能。
摘要（英）：

The invention relates to a preparation method of tunnel asphalt surface coat material, in particular to the preparation method of damping multi-hole noise eliminating tunnel asphalt surface coat material. The preparation method is characterized in that the invention comprises the steps as follows: (1) modified asphalt with high viscosity and high elasticity is prepared by the components with a weight ratio that modifier SBS: activating rubber powder: thickening compatibilizer: antioxidant: stabilizing agent is equal to 100:6.0 to 18.3:20.2 to 45.7:1.2 to 3.7:0.2 to1.4:0.4 to 1.9; the modified asphalt with high viscosity and high elasticity is obtained; (2) a flame retardant is added in the modified asphalt with high viscosity and high elasticity, the modified asphalt with high viscosityand high elasticity is heated to melt and the flame retardant is added, after being mixed for 3 to 9 minutes and being reversed in stillness for 15 to 30 minutes in 150 to 170 DEG C, the flame retarding modified asphalt with high viscosity and high elasticity is produced; (3) mineral aggregate: the flame retarding modified asphalt with high viscosity and high elasticity: fiber stabilizer being equal to the weight ratio of 100 : 36 to 5.2 : 0.1 to 0.4 is chosen to produce the damping multi-hole noise eliminating tunnel asphalt surface coat material. The invention has the functions of reducing noise, retarding flame and resisting slip.
