聚酯纤维在高速公路沥青混凝土中面层中的应用

Application of Polyester Fiber in Expressway Asphalt Pavement

结合具体高速公路工程实例,通过分析配合比试验结果,对掺入聚酯纤维后沥青混合料的各项性能进行了研究,从拌和、摊铺和碾压等方面阐述了掺入聚酯纤维后施工控制中应注意的问题。分析结果表明:掺加聚酯纤维是提高沥青路面性能的一种有效措施。

Combined with practical projects of expressway construction, this paper analyzes the mixture design and experimental results, and researches the performances of asphalt mixture which is adulterated with polyester fiber. This paper also discusses the method of construction control about mixing, paving and rolling after adding polyester fiber in asphalt mixture. The analysis result shows that adding polyester fiber is an effective measure to improve the performances of asphalt pavement.
