摘  要:纤维类型及用量对提高沥青混合料抗裂性能有重要影响.采用间接拉伸试验方法,以破坏拉伸应变和应变能作为评价指标,通过添加聚丙烯腈纤维、玄武岩纤维和木质素纤维制成纤维沥青混合料,比较不同纤维类型和纤维掺量对沥青混合料抗裂性能的影响.结果表明:对于破坏拉伸应变和应变能指标,从大到小依次为聚丙烯腈纤维、玄武岩纤维、木质素纤维;纤维掺量在0%~0.2%范围内,纤维掺量提高对于变形能力有较大提升.Fiber type and mixing amount has a significant impact on improving anti-cracking performance of asphalt mixture.In this paper,indirect tensile test is used to evaluate the anti-cracking performance of asphalt mixture with and destroy tensile strain and strain energy can be used as evaluation parameters.By adding polyacrylonitrile fiber,basalt fiberand lignin fiber to asphalt mixture,cracking resistance performance is compared with different types of fibers and fiber content of the asphalt mixture.The results show that,for the destruction of tensile strain and strain energy index,polyacrylonitrile fibers〉basalt fiber〉lignin fiber;For fiber content in the range of 0%-0.2%.Resistance to deformation is improved with increasing the fiber content.
