摘要
采用PR.M制备了高模量沥青混合料,并与添加聚酯纤雏的沥青混合料作对比分析。通过一系列室内试验,较为全面地分析了高模量沥青混合料的综合路用性能。结果表明,PR.M添加剂不仅可以大幅度提高沥青混合料的动态模量,改善其高温性能,也能够明显提高其抗水损害性能和低温抗裂性能,但抗疲劳性能有所下降。本研究成果可为PR.M高模量沥青混合在国内的推广应用提供参考依据。
High modulus asphalt mixture was prepared with PR. M additive, and was compared with the asphalt mixture added with polyester fibers. The comprehensive road performance of high modulus asphalt mixture was analyzed through a set of laboratory experiments. Results showed that PR. M additive could not only improve the dynamic modulus and the high temperature performance of asphalt mixtures greatly, but also significantly modify the water damage and the crack resistance ability; however, it weakens the fatigue resistance performance more or less. All the results would provide a reference for the wide application of high modulus asphalt mixture with PR. M in China.
