本文在室内马歇尔试验的基础之上,提出了聚合物纤维沥青混凝土的拌和试验方法.确定了不掺纤维的沥青混凝土（AC）和纤维掺量为0.2%、0.35%、0.5%的纤维沥青混凝土的最佳沥青用量.根据马歇尔试验确定的最佳沥青用量制备了沥青混凝土和不同掺量的聚合物纤维沥青混凝土,分别进行了高温车辙试验、低温小梁弯曲试验以及浸水马歇尔试验和冻融劈裂试验.试验结果表明：提出的“湿法”拌和工艺在相同的条件下可使聚酯纤维沥青混凝土混合料达到最理想的拌和效果,可有效避免纤维的结团现象：随聚酯纤维掺量的提高,马歇尔稳定度和毛体积密度变化呈先增大后减小的抛物线趋势,而流值和空隙率呈现相反的趋势；马歇尔方法设计的聚酯纤维沥青混凝土,虽然聚酯纤维掺量提高时,沥青混凝土的最佳油石比也同时增大,但纤维掺量和沥青最佳油石比的增长不成比例；对聚酯纤维沥青混凝土,聚酯纤维掺量与油石比增加量之比为1.05时,聚酯纤维和沥青可达到最佳的组合；聚酯纤维对沥青混凝土的高温稳定性具有显著影响,当聚酯纤维掺量与油石比增加量的比值接近1.05时,聚酯纤维对高温性能的改善效果达到最佳；马歇尔稳定度与车辙试验的动稳定度有良好的相关关系,因此,马歇尔稳定度能较好反映聚酯纤维沥青混凝土高温稳定性；在-40℃～10℃的温度范围内,随温度的降低,沥青混凝土及不同掺量聚酯纤维沥青混凝土的弯曲破坏强度均呈几乎线性降低趋势.聚酯纤维的添加虽不能从根本上改变沥青混凝土的温度敏感性本质,但明显改变了不同温度下弯曲破坏强度的大小；随着纤维掺量的提高,沥青混凝土抗弯拉强度提高幅度也不断增大；在-40℃～10℃的温度范围内,沥青混凝土及聚酯纤维沥青混凝土的抗变形能力均越来越差.但同等条件下,聚酯纤维的加入,使沥青混凝土的抗变形能力显著提高；掺加0.2%的聚合物纤维可使沥青混凝土浸水残留稳定度从86.59%提高到96.07%,提高幅度为11%；掺加0.2%的聚合物纤维以后,沥青混凝土试件的冻融劈裂抗拉强度比从80.8%提高到85%,水稳定性提高幅度达5.2%.

Indoor Marshall test based on the polymer fiber asphalt concrete mixing test methods. Determine the non-doped fiber asphalt concrete (AC) and the fiber content is 0.2%, 0.35%, 0.5% of fiber optimum asphalt content of asphalt concrete. Asphalt concrete of asphalt concrete, and with different contents of polymer fibers prepared according to the Marshall test to determine the optimum asphalt content, high temperature rutting test, the Low Wen Xiaoliang bending test and the immersion Marshall test and freeze-thaw splitting test. The experimental results show that: the proposed "wet" mixing process under the same conditions can make polyester fiber asphalt concrete mixture to achieve the best mixing effect, can effectively prevent the agglomeration phenomenon of the fiber: with polyester fiber content improve parabolic trend, Marshall stability and bulk density changes was first increases and then decreases, the flow value and porosity showed the opposite trend; Marshall designed polyester fiber asphalt concrete, polyester fiber content increased. asphalt concrete aggregate ratio also increases at the same time, the growth of the fiber content and the best asphalt-aggregate ratio out of proportion; polyester fiber asphalt concrete, polyester fiber content and Whetstone than the increase in the ratio of 1.05, polyester fibers and asphalt to achieve the best combination; polyester fiber has a significant impact on the high temperature stability of asphalt concrete, polyester fiber content and Whetstone than the increase in the ratio close to 1.05, polyester fiber for high temperature performance improvement to achieve the best; Marshall stability and rutting test the dynamic stability of the relationship, therefore, the Marshall stability can reflect the high temperature stability of polyester fiber asphalt concrete; -40 ° C to 10 ° C temperature range with decreasing temperature, the bending failure of the asphalt concrete for asphalt concrete and polyester fibers in different dosage strength showed an almost linear decreasing trend. Rate of polyester fiber to add, though not fundamentally change the temperature sensitivity of the nature of asphalt concrete, but significant changes in the size of the bending failure strength at different temperatures; With the improvement of the fiber content, the asphalt concrete flexural strength is also constantly increases; in the temperature range of -40 ° C ~ 10 ° C, the resistance to deformation of asphalt concrete and polyester fiber asphalt concrete is getting worse. Under the same conditions of polyester fiber, significantly increased resistance to deformation of the asphalt concrete; mixed with 0.2% of the polymer fiber allows asphalt concrete soaking residual stability increased from 86.59% to 96.07%, were increased by 11% ; after adding 0.2% of the polymer fibers, the freeze-thaw splitting tensile strength of asphalt concrete specimens increased from 80.8% to 85%, water stability increased to a rate of 5.2%.
