Solvated SBS rubber powder composite modified asphalt mixture and preparation method thereof
The invention discloses a solvated SBS rubber powder composite modified asphalt mixture and a preparation method thereof. The solvated SBS rubber powder modified asphalt mixture is prepared from the following components in parts by weight: 93 to 98 parts of aggregate, 4.5 to 6 parts of modified asphalt, 2 to 5 parts of mineral powder and 0.2 to 0.6 part of fiber. The solvated SBS rubber powder is adopted to replace an expensive SBS modifier, so that the prepared composite modified asphalt mixture is good in performance and low in cost, the rubber powder formed by grinding the waste tires is added, economic benefits and environmental benefits are good, meanwhile, the solvated SBS rubber powder composite modified asphalt mixture has good high-temperature stability, and the service life of the composite modified asphalt mixture is prolonged. The low-temperature anti-cracking performance and the durability are realized.
本发明公开了一种溶剂化SBS胶粉复合改性沥青混合料及其制备方法，所述溶剂化SBS胶粉改性沥青混合料包括以下重量份的组分：集料93‑98份，改性沥青4.5‑6份，矿粉2‑5份，纤维0.2‑0.6份。本发明采用溶剂化SBS胶粉代替昂贵的SBS改性剂，使其制备的复合改性沥青混合料的性能好且成本低，发明中加入了废旧轮胎研磨成的胶粉，经济效益及环境效益良好，同时溶剂化SBS胶粉复合改性沥青混合料具有良好高温稳定性，低温抗裂性能及耐久性。
