摘要:
在原材料物理力学性能试验的基础上,利用图解法并经过配合比调整和优化,得出沥青混合料AC-13 Ⅰ的配合比.通过不同纤维种类、不同纤维掺量下沥青混合料的马歇尔试验,得出纤维沥青混合料的最佳沥青用量OAC,然后通过高温车辙试验,研究纤维种类和掺量对沥青混合料动稳定度的影响,得出不同种类纤维的最佳掺量.结果表明:纤维能显著改善沥青混合料的高温性能;不同种类的纤维在沥青混合料中对应着不同的最佳掺量.最后,建立了考虑基体沥青混合料动稳定度与纤维掺量、纤维类型影响的纤维沥青混合料动稳定度的计算模型.
Abstract:

On the basis of the physical and mechanical properties test of raw materials, the mixing ratio of asphalt mixture AC-13 I was obtained by using the graphical method and adjusting and optimizing the mixing ratio. Through the Marshall test of asphalt mixture under different fiber types and different fiber content, the optimal asphalt dosage OAC of fiber asphalt mixture is obtained, and then the influence of fiber type and content on the dynamic stability of asphalt mixture is studied through high temperature rutting test, and the optimal amount of different types of fiber is obtained. The results show that the fiber can significantly improve the high temperature performance of asphalt mixture. Different kinds of fibers correspond to different optimal amounts in asphalt mixtures. Finally, a calculation model of the dynamic stability of the matrix asphalt mixture is established, considering the dynamic stability of the matrix asphalt mixture, the influence of fiber content and fiber type.
