Abstract:: 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.
