聚酯纤维对SMA性能影响的研究

Research on Influence of Polyester Fibers on SMA Performance

纤维复合材料是常用的道路工程材料之一 ,SMA是通过在沥青混合料中掺入纤维以提高混合料路用性能的一种典型复合材料。本研究以聚酯纤维、玄武岩以及 SBS改性沥青作为原材料 ,对不同纤维掺量下的 SMA混合料的路用性能进行试验和分析 ,利用多重回归分析 ,预测出了聚酯纤维在 SMA中的最佳掺量。

The fiber composite is one of the commonly used engineering materials,and the fibers are also successfully used in the asphalt mixture. Polyester fibers used in the SMA mixtures are a good example. But now there are a few researches on the optimum content of the fiber. This research mainly uses polyester fibers, basalt and SBS modified asphalt as row materials, according to the volume and pavement performance of SMA mixtures with different contents of fibers, the test results are analyzed and compared. The fiber reinforcement mechanism is simply interpreted and the optimum contents of the polyester fibers are given by using multiple regression analysis method.
