纤维和车辙剂对沥青混合料路用性能的影响研究

为了探究纤维和车辙剂共同作用对沥青混合料路用性能的影响，将聚酯纤维和抗车辙剂掺入沥青混合料中，通过宏观性能试验对沥青混合料的高低温和水稳性能进行研究。结果表明，聚酯纤维单掺、抗车辙剂单掺、两种材料复掺均可改善沥青混合料的高温和水稳性能，聚酯纤维可有效改善沥青混合料的抗弯拉性能，但抗车辙剂对沥青混合料的最大弯拉应变不利。车辙剂和聚酯纤维复掺对沥青混合料的改善效果更佳。

Influence of fiber and rutting agent on pavement performance of asphalt mixture

In order to explore the influence of fiber and rutting agent on pavement performance of asphalt mixtures, polyester fiber and anti-rutting agent are mixed into asphalt mixtures, and the high and low temperature and water stability of asphalt mixtures is studied through series of macroscopic performance tests. The results show that the high temperature and water stability of asphalt mixtures can be improved by single addition of polyester fiber, single addition of anti-rutting agent and composite addition of both materials. Polyester fiber can effectively improve the flexural and tensile properties of asphalt mixture, but the rutting agent is not conductive to the maximum flexural and tensile strain of asphalt mixtures. The combination of rutting agent and polyester fiber has better improvement effect on asphalt mixtures.
