聚丙烯纤维改善沥青混合料性能的研究

The study on improving asphalt concrete service properties with polypropylene fiber

通过对沥青混合料中加入聚丙烯纤维的研究 ,系统分析了聚丙烯纤维改善沥青混合料的高温稳定性、低温抗裂性等 ,提出了强度形成机理以及纤维改善路面使用性能的因素 。

This paper presents the comparison test and study on the effects of using polypropylene in asphalt concrete to improve the service properties. All these characters including strength mechanism, high and low temperature stabilities, anti-fatigue capacity and water stability are studied and contested with normal asphalt concrete.
