摘要
通过对木质素、聚酯、聚丙烯、玄武岩和海泡石纤维SMA混合料的路用性能及改性机理对比分析,研究了不同纤维对SMA混合料的适用性。结果表明,不同类型的纤维对SMA混合料的高温稳定性、低温抗裂性、水稳定性以及疲劳抗裂性均有显著影响,其中海泡石纤维的综合路用性能最优,聚丙烯纤维的低温抗裂性和抗疲劳耐久性较好,而木质素纤维的低温抗裂性和抗疲劳性能最差。
The impact of lignin, polyester, polypropylene, basalt and sepiolite fiber on SMA mixture＇s pavement performance was studied. The results show that all these types of fibers have significant impact on the SMA mixture＇s high temperature stability, crack resistance at low temperature, water stability and fatigue crack resistance, among which sepiolite fiber has the best performance in general. Polypropylene shows good results in terms of crack resistance at low temperature and fatigue crack resistance, while lignin has the worst performance in these aspects.
