摘　　要：介绍了纤维沥青混合料的作用机理及纤维在沥青混合料中的应用情况,结合排水性沥青混合料试验对试验用纤维的指标进行分析,对不同种类纤维的混合料性能作对比研究.试验表明,纤维在减少排水性沥青混合料的析漏方面功能显著,纤维的力学增强作用只有在掺量较大时才能体现出来.从混合料析漏试验来看,木质素纤维的抗析漏效果最好,聚合物化学纤维次之.矿物纤维又次之,从对马歇尔稳定度和劈裂强度的改善效果来看,矿物纤维最优,聚合物化学纤维次之,木质素纤维又次之,对动稳定的影响则在不同掺量下呈现不同的规律.The action mechanism of fiber asphalt mixture and the application of fiber in asphalt mixture were introduced. The indexes of fiber used in the experiment were analyzed in combination with the experiment of drainage asphalt mixture, and the performance of different kinds of fiber mixture was compared and studied. The test shows that fiber plays a significant role in reducing leakage of drainage asphalt mixture, and the mechanical reinforcement effect of fiber can only be shown when the content of fiber is large. From the mixture leakage test, lignin fiber has the best leakage resistance effect, followed by polymer chemical fiber and mineral fiber. From the improvement effect on Marshall stability and splitting strength, mineral fiber is the best, followed by polymer chemical fiber and lignin fiber, and the influence on dynamic stability shows different rules under different dosage.
