针对聚合物纤维改性Superpave混合料特点,通过不同刺量聚酯纤维改性Superpave沥青混合料的马歇尔试验、水稳定性和高温动稳定度试验,综合工程经济性,确定合适的纤维剂量为1.5‰.足尺疲劳试验和低温弯曲试验结果表明:聚合物纤维改性Superpave沥青混合料具有很强的低温抗裂性和抗反射裂缝能力,聚酯纤维改性Superpave混合料适宜于铺筑在旧路罩面中.最后,提出了合理的施工工艺;渗水性试验表明:这类混合料应加强施工压实.

According to the characteristics of polymer fiber modified Superpave mixture, through the Marshall test, water stability and high temperature dynamic stability test of Superpave asphalt mixture modified with different amounts of polyester fiber, comprehensive engineering economy, the appropriate fiber dose was determined to be 1.5‰. Polyester modified Superpave mixtures are suitable for paving in old road coverings. Finally, a reasonable construction process is proposed; The water permeability test shows that this kind of mixture should strengthen the construction compaction.
