摘　　要：沥青路面在日常养护和改扩建施工时,会产生大量的废旧材料。由于旧料中含有沥青成分,当作垃圾处理会污染环境。因此将这些旧料再生,既减轻了环境污染,又减少了材料消耗。再生技术的应用是实现公路可持续发展的重要手段。现行规范将沥青路面再生方式分为厂拌热再生、就地热再生、厂拌冷再生、就地冷再生和全深式冷再生5种。本文对泡沫沥青就地冷再生技术在工程实际中的应用进行具体说明及分析。Asphalt pavement generates a large amount of waste materials during daily maintenance and expansion construction.Due to the presence of asphalt in the old materials,treating them as garbage can pollute the environment.Therefore,recycling these old materials not only reduces environmental pollution but also reduces material consumption.The application of regeneration technology is an important means to achieve sustainable development of highways.The current regulations divide the regeneration methods of asphalt pavement into five types:plant mixed hot regeneration,on-site geothermal regeneration,plant mixed cold regeneration,on-site cold regeneration,and full depth cold regeneration.In this paper,the application of foam asphalt in situ cold recycling technology in engineering practice is described and analyzed in detail.
