摘　　要：本文依托真实项目施工组织与台账数据,建立了全寿命周期计算模型,对比了厂拌冷再生技术与其替代的基准技术——传统的ATB-25型沥青稳定碎石基层施工方案的减碳量,分析了筑路材料、能源燃料的碳排放因子以及材料运距的敏感性。结果发现,相比于传统的ATB-25基层方案,厂拌冷再生基层方案能够在混合料生产、拌和等阶段可极大地减少碳排放量,减排率约为21.1%,减排效益显著,水泥、乳化沥青的排放因子与原材料运距是敏感因素。Based on the real data of construction organization and records,this paper establishes the life-cycle carbon emission calculation model,compares the carbon reduction between the scheme of plant mixed cold recycling technology and the alternative base scheme-traditional ATB-25 asphalt stabilized crushed-stone base,and analyzes the sensitivity of construction materials,carbon emission factors of energies,and the delivery distance.The results show that compared to the traditional ATB-25 scheme,the scheme of plant mixed cold recycling technology could reduce a large number of carbon emission from the production and mixture of mixed materials with a reduced rate of 21.1%.The decarbonization benefit is great.
