冷再生技术是近年来道路维修改造应用的一项新技术,而乳化沥青是冷再生技术中常用的稳定剂,以某改建工程现场回收旧沥青混合料为试验原料,设计了冷再生混合料细粒式A级配方案,并试验对比分析了乳化沥青和水泥—乳化沥青两种添加剂冷再生混合料的力学性能和水稳定性。试验结果表明:加入适当添加剂的冷再生混合料性能满足道路的基层或底基层的技术指标要求,明显提高了材料的性能,可在道路维修改建工程中应用,在获得良好社会及经济效益的同时,也减少了对环境的污染。
Cold Recycling Technology is a new technology used in road maintenance and rejuvenation in recent years. Emulsified asphalt is a commonly used stabilizer in cold rejuvenation technology. Based on the recovery of old asphalt mixture on the site of a rebuilding project, Granular A grade formula program and test the mechanical properties and water stability of the cold reclaimed mixture of emulsified asphalt and cement - emulsified asphalt two additives were compared. The test results show that the properties of cold reclaimed composites with appropriate additives can meet the technical requirements of the grassroots or subsoil of the road and obviously improve the performance of the materials. It can be applied in the road maintenance and reconstruction project. While obtaining good social and economic benefits , But also reduce the pollution of the environment.
