摘要： 通过试验对比研究采用橡胶粉制备性能更优的高黏改性沥青。结果表明：采用高目数橡胶粉复配适量的SBS、烯烃聚合物以及石油树脂可以制备满足规范要求的高黏改性沥青，掺配比例为12%的80目橡胶粉、6% SBS、2% Sasolbit蜡、2%萜烯树脂。为降低成本，进一步研究了采用活化橡胶粉制备高黏改性沥青；试验得出采用25%脱硫胶粉(活化程度50%左右)、6% SBS、2% Sasolbit 蜡、2%萜烯树脂的添加比例，制备得到的高黏改性沥青的性能得到大幅提升，同时可较大程度降低材料成本。

Abstract: The feasibility of preparing high-viscosity modified asphalt with better performance by using rubber powder was studied by contrastive experiments. The results show that the high-viscosity modified asphalt meeting the requirements of the specification can be prepared by blending high mesh rubber powder with appropriate SBS, alkene polymer and petroleum resin, and the blending ratio was adding 12% 80 mesh rubber powder, 6% SBS, 2% Sasolbit wax and 2% terpene resin. In order to further reduce the cost, the feasibility of preparing high-viscosity modified asphalt from activated rubber powder was preliminarily explored. The test results show that the performance of high-viscosity modified asphalt can be greatly improved and the material cost can be greatly reduced by adding 25% desulfurized rubber powder (activation degree is about 50%), 6% SBS, 2% Sasolbit wax and 2% terpene resin.
