摘要:

作為一種新型路面材料，高摩擦道路表面處治（high friction surface treatment，HFST）材料由高耐磨集料和粘結劑組成，用于解決傳統(tǒng)路面材料修筑的彎道、長大縱坡等特殊路段因路面抗滑能力衰減過快導致的安全性問題。為了推動HFST技術在我國路面養(yǎng)護中的發(fā)展，提高道路安全性，降低養(yǎng)護投資成本，回顧了相關學者對HFST材料抗滑性能的研究現(xiàn)狀，綜述了高耐磨集料的物理、力學性能，評價了HFST集料的耐磨特性，分析了礦物組成對集料耐磨性能的影響，闡明了高耐磨集料長期磨光機制；概述了用于HFST的粘結劑性能，分析不同類型環(huán)氧樹脂粘結劑的適用性；總結集料種類、集料粒徑、集料摻配方式、粘結劑種類、厚度等HFST材料組成設計關鍵參數(shù)對其抗滑性能的影響規(guī)律，提出了HFST材料組成建議；總結分析了HFST試驗路段長期抗滑衰變特性以及經濟效益，最后探討了現(xiàn)有HFST研究存在的問題，并對后續(xù)研究提出了建議。

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�瞨esistant 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.
