摘　　要：探讨了聚丙烯纤维掺量对水泥混凝土路面抢修材料性能的影响，对耐磨性能和抗渗性能进行了系统研究。结果表明：当聚丙烯纤维的体积掺量为0．1％～0．2％时，水泥混凝土路面抢修材料的流动度、终凝时间、抗折强度和抗压强度均满足施工要求；抗渗性能无明显改变；耐磨性能明显提高，且2h，28d及90d的耐磨性能均高于普通混凝土。The effect of mixing amount of polypropylene fiber on cement concrete pavement repair material properties, the wear resistance and impermeability were studied. The results showed that when the polypropylene fiber volume content was 0. 1% - 0.2% , the initial fluidity, final setting time, flexural strength and compressive strength of the cement concrete pavement repair material met the construction requirements; impermeability had no obvious change; wear resistance improved obviously, and wear- resisting performance of 2h, 7d and 28d were higher than ordinary concrete.
