纤维沥青混合料增强作用机理分析

Discussion on the reinforcement mechanism of fiber-reinforced asphalt mixture

纤维复合材料是常用的工程材料之一,而在沥青混合料中添加纤维已取得了成功的经验。通过对普通沥青混合料的组成结构和强度作用特性的分析,表明要改善沥青混合料的性能可通过添加纤维来改善沥青的性能入手,并讨论了纤维增强沥青混合料作用机理的有关理论与观点,分析了纤维沥青混合料同其它纤维复合材料性能特性存在差异的原因及纤维增强效果,分析了纤维沥青混合料的增强机理。

The fiber composite is one of the commonly used engineering materials,and the fibers are also successfully used in the asphalt mixture. In the paper,the components and strength characteristics of the normal asphalt mixture are analyzed,and it is considered that the performance of the asphalt mixture can be enhanced by improving the asphalt character. The strengthening mechanism of the fiberreinforced asphalt mixture is expatiated with the related theories,the difference between the fiberreinforced asphalt mixture and other fiber composites discussed,and the reinforcement mechanism of the fibers in the asphalt mixture analyzed.
