摘要
采用普通沥青、玄武岩纤维沥青、聚丙烯纤维沥青和复掺纤维沥青等4种混合料进行耐久性试验分析,主要考察了材料多重老化高温性能、多重浸水稳定性能和多重冻融劈裂性能。研究结果显示:普通沥青混合料受高温老化影响最大,掺加玄武岩纤维可缓解材料老化过程;复掺纤维可以促进沥青混合料内部结构的稳定,受水损伤和冻融损伤的影响较低,可提升沥青混合料的耐久性。
The durability analysis on ordinary asphalt,asphalt mixture with basalt fiber,polypropylene fiber and compound fiber asphalt were carried out.The material’s multiple aging high temperature performance,multiple water immersion stability performance and multiple freeze-thaw split performance are mainly investigated.Research has shown that the aging of ordinary asphalt mixtures are mostly affected by high-temperature,and basalt fiber can alleviate the aging process of materials.The compounded fiber can promote the stability of the internal structure of the material and have lower impact on water damage and freeze-thaw damage so that durability of asphalt mixture can be improved.
