沥青混合料全过程碳排放减排决策体系研究

Research on the Decision-making System for Carbon Emission Reduction throughout the Entire Process of Asphalt Mixture Production

摘要:

降碳减排不仅已经上升至国家战略，也成为各行各业重点研究与发展的方向。以沥青道路工程领域为例，道路材料及施工降碳减排已成为主要研究方向，并取得了一定的研究成果，但是鲜有关于基于沥青混合料全过程碳排放及决策研究。基于从材料准备到运行维护及拆除处置等5个阶段碳排放清单和计算因子，探讨与分析了占比率法、AHP法和比较分析法3种碳排放权重计算方法，最终优选出计算简便、结果直观的占比率法，并结合碳排放清单和计算因子，分析与提出了材料准备、生产拌合、施工摊铺、运行维护和拆除处置的降碳减排措施，以期为行业践行降碳减排的社会责任提供一定的参考。

Abstract:

Carbon reduction and emission mitigation have not only risen to the level of national strategy but also become a key research and development focus across various industries. Taking the asphalt road engineering field as an example, carbon reduction and emission mitigation in road materials and construction have emerged as primary research directions, yielding certain achievements. However, there is a scarcity of studies on the full life-cycle carbon emissions and decision-making in asphalt mixtures. Based on the carbon emission inventory and calculation factors across five stages, including material preparation, operation and maintenance, and demolition disposal, three carbon emission weight calculation methods: the proportion method, the Analytic Hierarchy Process (AHP), and the comparative analysis method are discussed and analyzed in this paper. Ultimately, the proportion method which is simple to calculate and provides intuitive results is selected as the optimal approach. Combined with the carbon emission inventory and calculation factors, methods for material preparation, production mixing are analyzed and proposed in this paper.The carbon reduction and emission reduction measures for construction paving, operation maintenance, and demolition disposal are aimed at providing some reference for the industry to fulfill social responsibility of carbon reduction and emission reduction.
