| 摘 要： | 为比较不同掺量、不同类型抗车辙剂对沥青混合料改性效果的影响，分别对掺入PR和RA抗车辙剂的改性沥青混合料和基质沥青混合料路用性能进行了对比试验。分析结果表明:掺加抗车辙剂的沥青混合料动稳定度和劈裂强度明显增强，抗疲劳性能的改善并不明显，大部分改性沥青混合料的低温性能和自愈能力较差。

| Abstract: | For the purpose of comparing the effects on asphalt mixtures modified by anti-rut agents in different proportions and types, the comparative tests were carried out respectively in relation to the pavement performance of the asphalt mixtures modified by PR and RA anti-rug agents, and the basic asphalt mixture. The results show that anti-rut agent modified asphalt mixture has obviously increased dynamic stability and splitting strength, but unconspicuously improved fatigue property; and most of the modified mixtures have poor low temperature performance and self-healing ability. With all considerations, the modification effect of PR is slightly superior to that of RA. |
