| 摘要: |
| 基于车辙试验和浸水马歇尔试验,研究了聚酯纤维和SBS改性剂对沥青混合料高温稳定性和水稳定性的影响.结果表明:聚酯纤维适宜掺量为0.20%～0.25%(质量分数);采用聚酯纤维和SBS改性剂对沥青混合料进行综合改性,可使其路用性能更趋完善. |

| Abstract: |
| Based on wheel tracking tests and immersion Marshall tests,the effect of polyester fiber and SBS additive on high temperature stability and water stability of asphalt mixture were investigated.Results indicate that the appropriate polyester fiber content is between 0.20% and(0.25%)(by mass).Asphalt mixture modified by both polyester fiber and SBS additive make road(application performance) better. |
| Key words: polyester fiber,asphalt modified by SBS additive,high temperature stability,water stability |
