| 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。

| Abstract: | 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 resistan... |
