聚酯纤维对沥青砼路用性能作用分析

Analysis of Polyester fiber on the role of asphalt pavement performance

随着我国公路交通的快速发展,交通量迅速增加、车速提高、交通渠化、轴载增加以及普遍的车辆超载现象,对高等级公路沥青路面所用的沥青混合料性能提出了更高的要求。有关研究表明,聚酯纤维的加入可提高混合料的综合路用性能,并能够在一定程度上改善沥青砼路面的长期使用性能。本文在此基础上分析了聚酯纤维对沥青砼路用性能作用机理。

With the rapid development of China＇s transportation, the general phenomena such as sharply increase in traffic volume, significantly improved speed, traffic canalization, increasing axle load and overloading of vehicles has set higher requirements for asphalt pavement performance of asphalt mixture used on the highway. Relevant studies show that polyester fiber can increase the overall pavement performance of asphalt mixture and be able to improve the long - term performance of asphalt concrete pavement to a certain extent. On this base, this paper analyzes the modification mechanism of polyester fiber on asphalt pavement performance.
