摘　　要：作为一种新型路面材料,高摩擦道路表面处治(high friction surface treatment, HFST)材料由高耐磨集料和粘结剂组成,用于解决传统路面材料修筑的弯道、长大纵坡等特殊路段因路面抗滑能力衰减过快导致的安全性问题。为了推动HFST技术在我国路面养护中的发展,提高道路安全性,降低养护投资成本,回顾了相关学者对HFST材料抗滑性能的研究现状,综述了高耐磨集料的物理、力学性能,评价了HFST集料的耐磨特性,分析了矿物组成对集料耐磨性能的影响,阐明了高耐磨集料长期磨光机制;概述了用于HFST的粘结剂性能,分析不同类型环氧树脂粘结剂的适用性;总结集料种类、集料粒径、集料掺配方式、粘结剂种类、厚度等HFST材料组成设计关键参数对其抗滑性能的影响规律,提出了HFST材料组成建议;总结分析了HFST试验路段长期抗滑衰变特性以及经济效益,最后探讨了现有HFST研究存在的问题,并对后续研究提出了建议。As a new type of pavement material, high friction surface treatment(HFST) materials is composed of high wear-resistant aggregate and polymer resin binder, which is used to solve the safety problems caused by the rapid attenuation of skid resistance of special sections such as curves and large longitudinal slopes built by traditional pavement materials. In order to promote the development of HFST technology in pavement maintenance in China, improve road safety and reduce the cost of maintenance investment, the research status of skid resistance of HFST materials by relevant scholars are reviewed in this paper. Physical and mechanical properties of high wear-resistant aggregates are summarized, the wear resistance of HFST aggregates is evaluated, the influence of mineral composition on wear resistance is analyzed, and the long-term polishing mechanism of high wear-resistant aggregates is clarified. Properties of binders used for HFST are also mentioned, and the suitability of different types of epoxy resin binders is summarized. The influence of the key parameters of HFST material composition design on its anti-skid performance is analyzed, such as aggregate type, aggregate particle size, aggregate blending method, binder type, thickness, etc., and recommendations of HFST material composition are put forward. The long-term skid resistance attenuation characteristics and economic benefits of HFST test strips are presented as well. Finally, the existing problems of HFST studies and proposals for further research are discussed.
