摘要
首先介绍高寒低温地区沥青混凝土裂缝产生原因和危害,其次阐述了聚酯纤维在沥青混合料中作用机理,并对掺加不同用量聚酯纤维的沥青混合料试件与普通沥青混凝土试件进行低温弯曲蠕变试验和小梁弯曲试验,在取得对应的低温指标后,得到了在聚酯纤维沥青混合料不同温度试验指标,并归纳了聚酯纤维在提高和加强沥青混凝土路面的低温抗裂性能的作用机理和显著效果。
This paper introduces the causes of high and cold area asphalt concrete cracks and harm,followed by explication of mechanism of polyester fiber in the asphalt mixture.Next mixing different amount of polyester fiber asphalt concrete and ordinary asphalt concrete at low temperature are experimenting with bending creep test and trabecular bending test,after obtaining the corresponding low-temperature indicators,test indicators of asphalt mixture with polyester fiber are obtained at different temperatures,and mechanism of polyester fiber in the improving and strengthening the low temperature cracking performance of asphalt concrete pavement and significant effect are summarized.
