摘要:

为探讨合成聚合物纤维对沥青混合料耐水性的影响,先由马歇尔试验和车辙试验确定纤维的最佳掺量,然后按照现行规范JTG F40-2004规定的浸水马歇尔试验和冻融劈裂试验评价合成聚合物纤维对沥青混合料耐水性的改善效果.试验结果表明,聚酯纤雏、聚丙烯腈纤雏对沥青混合料的浸水马歇尔残留稳定度分别提高了4.4%和7.8%;在50次和75次压实功下,聚酯纤维对沥青混合料的冻融劈拉强度比分别提高了4.5%和3.1%;聚丙烯腈纤维分别提高了6.9%和8.6%.

Abstract:

In order to explore the effect of synthetic polymer fibers on the water resistance of asphalt mixture, the optimal amount of fiber was determined by Marshall test and rutting test, and then the improvement effect of synthetic polymer fiber on the water resistance of asphalt mixture was evaluated according to the water-immersion Marshall test and freeze-thaw splitting test specified in the current standard JTG F40-2004. The test results showed that the residual stability of polyester fiber brood and polyacrylonitrile fiber brood on asphalt mixture was increased by 4.4% and 7.8%, respectively. Under 50 and 75 compaction times, the freeze-thaw splitting strength ratio of polyester fiber to asphalt mixture increased by 4.5% and 3.1%, respectively. Polyacrylonitrile fiber increased by 6.9% and 8.6%, respectively.
