排水性沥青路面用高黏改性剂研究进展

Research progress on high viscosity modifiers for porous asphalt pavement

排水性沥青路面是一种具有排水、降噪和抗滑等功能的新型沥青路面。针对排水性沥青路面所用高黏改性剂,重点综述了热塑性弹性体、橡胶、纤维、树脂和纳米材料等物质在高黏改性剂中的应用,并对其优势及存在的问题进行了讨论。最后,对排水性沥青路面用高黏改性剂的发展方向进行了展望。

Porous asphalt pavement is a new type of asphalt pavement with some properties（such as draining,noise reduction,and skid resistance）. The application of some materials（such as thermoplastic elastomer,rubber,fiber,resin,and nano-materials）in high viscosity modifiers,which were used for porous asphalt pavement,wasreviewed,and their advantages and existing problems were discussed. Finally,the development direction of highviscosity modifiers for porous asphalt pavement was expected.
