摘　　要：为了研究聚丙烯纤维对道面混凝土耐久性的影响,应用冲击、碳化、抗老化、抗硫酸盐和耐磨等试验方法,进行了素混凝土和聚丙烯纤维混凝土的对比试验,研究了聚丙烯纤维的作用机理。结果表明:聚丙烯纤维能有效地提高道面混凝土的抗冲击能力和耐磨能力,有效地控制道面混凝土的碳化,降低了硫酸镁溶液侵入,聚丙烯纤维道面混凝土不存在老化问题。In order to study durability of pavement polypropylene fiber reinforced cement concrete, some systematic test on shock resistance, aging resistance, carbonization resistance and sulfate resistance and abrasion resistance for concrete were done, the test results between polypropy- lene fiber reinforced cement concrete and cement concrete were compared, the strengthening mechanism of polypropylene fiber was studied.Analysis result indicates that polypropylene fiber can improve the shock resistance and abrasion resistance, decrease the carbonization and magnesium sulfate erosion.Pavement polypropylene fiber reinforced cement concrete has no aging.
