摘　　要：为改善沥青的技术指标,增加废旧塑料的回收利用率,以PE塑料颗粒与基质沥青高温剪切制备改性沥青,通过3因素3水平的正交试验确定以高温剪切乳化机制备PE改性沥青的最佳工艺,并分析PE塑料颗粒掺量对沥青3大指标的影响以确定最佳掺量。In order to improve technical indices of asphalt and increase recovery rate of waste plastics,this paper prepares the modified asphalt with PE plastic particles and matrix asphalt through high-temperature shear,determines the optimal process in preparation of PE modified asphalt with high-temperature shear emulsifying machine via the orthogonal test of 3-factor-3-level,and analyzes the influences of dosage of PE plastic particles on 3 indices of asphalt to determine the optimal dosage.
