| 摘要: |
| 以合新70号沥青为基质沥青、多层共挤膜废料(r MCEFS)和SBS为改性剂、POE g GMA为相容剂，通过熔融共混法制备r MCEFS/SBS复合改性沥青，并探讨r MCEFS外掺量对复合改性沥青的常规性能、流变性能和微观结构的影响.结果表明：随着r MCEFS外掺量的增加，复合改性沥青的车辙因子逐渐增加；当r MCEFS外掺量为基质沥青质量的3%时，r MCEFS/SBS复合改性沥青的针入度和软化点指标达到聚合物改性沥青SBS类(Ⅰ类)的I D级别，且体系弹性回复能力最优. |

| Abstract: |
| Taking the Hexin No.70 asphalt as matrix, recycled multilayer co extrusion film scraps(r MCEFS) and styrene butadiene styrene(SBS) as modifier, POE g GMA as a compatibilizer, r MCEFS/SBS modified asphalt composites were prepared by melt blending. The classical performance, rheological properties and microscopic structure of r MCEFS/SBS modified asphalt composites with different contents of r MCEFS were investigated. The results show that the rutting factor of r MCEFS/SBS modified asphalt composites increases with the increase of r MCEFS contents. With the addition of 3% of r MCEFS(by mass of asphalt matrix), r MCEFS/SBS modified asphalt composites achieve the SBS polymer modified asphalt types(type Ⅰ) I D level in the penetration and softening point index, and show the optimal elastic recovery ability. |
