摘　　要：沥青路面再生技术具有循环利用资源、节约能源、保护环境等优势,已成为实现低碳交通的重要途径之一,在我国推广应用沥青路面再生技术已势在必行。泡沫沥青冷再生技术,可充分对旧路路面材料进行回收利用,从而达到低碳、节能的效果。同时,通过泡沫沥青冷再生技术可以实现原有半刚性基层转换为柔性基层,从而延长道路使用寿命。近年来对于泡沫沥青冷再生技术进行深入研究,基于国内外最新研究成果,综述对比分析其优势与不足,对于促进我国该项技术的发展,具有重要的价值。The asphalt pavement recycling technology has advantages such as recycling resources, saving energy and protecting environment. As one of the important ways to realize low-carbon transportation, it is imperative to promote and apply the asphalt pavement recycling technology in China. The foamed asphalt cold recycling technology can fully recycle and utilize old road materials to achieve effects of low carbon and energy saving, it also can transform the semi-rigid base to flexible base so as to prolong the service life of the road.In recent years, the foamed asphalt cold recycling technology has been deeply studied at home and abroad, on this basis, this paper comprehensively compares and analyzes the advantages and shortcomings of this technology, which has crucial value for improving its development.
