木质素纤维材料在沥青混合料中的应用较多,它能够稳定沥青结合料,但对于SMA-5这种超细粒径混合料的影响以往资料中很少提及。同样对于这种新型的沥青混合料,结合料对其性能也将产生不同方面的影响。针对木质素纤维的作用与沥青结合料的影响,以SMA-5沥青混合料为载体,进行室内对比试验和试验段验证,期望能进一步了解和掌握SMA-5混合料的性能特点,研究木质素纤维与沥青结合料对于SMA-5的性能影响,为完善其配合比设计提供参考依据。 Lignin fiber material in asphalt mixture more applications, it can stabilize the asphalt binder, but for the SMA-5 this ultra-fine particle size mixture in the past rarely mentioned. Also for this new type of asphalt mixture, the binder will have different effects on its performance. In view of the effect of lignin fiber and the influence of asphalt binder, SMA-5 asphalt mixture was used as a carrier to conduct indoor comparative test and test section verification. It is hoped that the performance characteristics of SMA-5 mixture can be further understood and grasped, Fiber and asphalt binder for the performance of SMA-5, to improve the design of its reference to provide a reference.
