玄武岩纤维在长上坡路段沥青路面中的应用

The Application of Basalt Fiber in Asphalt Pavement of Long Uphill Section

在高温及重荷载的共同作用下,车辙已成为公路沥青混凝土面层的主要病害之一,也是难以有效解决的一大难题。车辙基本发生在主车道纵向轮迹上,尤其是长大上坡、道路平交道口及收费站进出口处等速度较慢部位。而玄武岩纤维是一种纯天然、抗车辙能力和抗老化性强的新型环保材料,本文结合了沥青混合料及玄武岩矿物纤维的特点进行了玄武岩纤维沥青混合料性能评价,并与不掺加玄武岩矿物纤维的沥青混合料进行对比分析,以便对玄武岩矿物纤维在沥青路面中的应用提供参考。

In a high temperature and heavy loading,rut highway asphalt concrete pavement has become one of the main diseases,it is also a major problem which is difficult to solve effectively.Rut fundamentally place in vertical wheel tracks on the main lane,especially long uphill,road level crossing,toll stations＇ import and export department,which are slower parts.Basalt fiber is a kind of pure natural,rut resistance and strong ageing resistance of new environmental protection materials,this paper combines the asphalt mixture and basalt fiber characteristics of the basalt fiber performance evaluation of asphalt mixture with and without adding basalt fiber asphalt mixture were analyzed,so that the application of basalt fiber in asphalt pavement provides the reference.
