摘　　要：通过室内试验 ,研究了掺加 PR PL ASTS抗车辙剂的 AC- 13I型沥青混合料的配合比设计及其高温稳定性、低温抗裂性和水稳定性。通过对比分析 ,发现掺加 PR PL ASTS抗车辙剂的沥青混合料性能得到了显著改善 ,特别是其沥青混合料的动稳定度比 SBS改性沥青混合料提高了 2 7.5 6 %。结果表明 PR PL ASTS抗车辙剂适合铺筑在大交通量、重载较多的路段以及夏季气温较高地区的高速公路上。According to the Qingbian-Wangquanliang Section of Yin-Qing Expressway, the performances of AC-13I asphalt mixture intermingled with Anti-Rut Agent PR PLASTS, such as high temperature stability, crack resistance at low temperature and water stability are studied in this paper.The performances of asphalt mixture intermingled with Anti-Rut Agent PR PLASTS are improved very much as compared with SBS modified asphalt mixtures. Especially, its dynamic stability is increased by 27.56% than SBS modified asphalt mixtures. The results showe that Anti-Rut Agent PR PLASTS could be used in expressway with heavy truck traffic or in high temperature areas.
