摘要
采用胶粉复合改性沥青与SBS改性沥青在室内开展相关材料检测和配合比设计试验,选用相同级配的AC-20C沥青混合料,进行两者高温稳定性能、低温性能、水稳定性等路用性能对比评价。结果表明:胶粉复合改性沥青混合料高温抗车辙性能优于SBS改性沥青混合料,其他路用性能指标没有显著性差异。
Use rubber powder composite modified asphalt and SBS modified asphalt to carry out related material testing and mix ratio design tests indoors, and select AC-20C asphalt mixture of the same gradation to conduct comparative evaluation of road performance of high temperature stability, low temperature performance, water stability, etc. The results show that the high-temperature rutting resistance of the rubber powder composite modified asphalt mixture is better than that of the SBS modified asphalt mixture, and there is no significant difference in other road performance indicators.
