为了研究聚酯纤维对沥青混合料性能的影响规律,分别制成了聚酯纤维掺量为0、0.2%、0.35%和0.5%的沥青混合料。采用AC-13型级配沥青混合料研究4种掺量不同的聚酯纤维对沥青混合料高温性能、低温性能与水稳定性的影响。研究结果表明:随着聚酯纤维掺量的变化,沥青混合料性能变化明显,显著影响沥青混合料的路用性能。
In order to study the influence of polyester fiber on the performance of asphalt mixture, asphalt mixture with 0,0.2%, 0.35% and 0.5% of polyester fiber content was made respectively. The effect of four kinds of polyester fiber with different content on the high temperature performance, low temperature performance and water stability of asphalt mixture was studied by using AC-13 gradation asphalt mixture. The results show that with the change of the content of polyester fiber, the performance of asphalt mixture changes obviously, which significantly affects the road performance of asphalt mixture.
