Research on Carbon Emission Calculation and Carbon Reduction Technology in OGFC Production Process

针对降低道路沥青混凝土路面设计、生产、施工、管养过程的碳排放问题,开展对排水性沥青面层OGFC沥青混合料包括原材料准备、原材料运输到生产基地、混合料生产拌和阶段在内的生产过程碳排放计算方法进行研究。将排水性沥青面层OGFC沥青混合料的生产过程划分为材料准备和混合料生产拌和两个阶段,根据混合料的配合比设计、材料准备方案、生产工艺等,按排放因子法计算系统边界内各阶段的碳排放,分析各分项碳排放占比,提出合适的碳减排措施。以上海市浦东新区高等级道路金海路改建工程为例,对研究提出的碳排放计算方法和碳减排技术进行实际应用分析,结果显示碳减排效果比较显著。

Aimed at reducing the carbon emission in the process of design,production,construction and maintenance of asphalt concrete pavement,the carbon emission calculation method of OGFC asphalt mixture in the production process including raw material preparation,raw material transportation to the production base and mixing stage of the mixture is studied.The production process of OGFC asphalt mixture for drainage asphalt pavement is divided into two stages of material preparation and mixture production and mixing.Based on the mix design,material preparation scheme,production process,etc.of the mixture,the carbon emissions of each stage within the system boundary are calculated by using the emission factor method.According to the proportion of carbon emissions in each sub item,the appropriate carbon emission reduction measures are analyzed and proposed.Taking Shanghai Pudong New District High-class Road Jinhai Road Reconstruction Project as an example,the practical application of the carbon emission calculation method and carbon emission reduction technology proposed in this study is analyzed.The results show that the carbon emission reduction effect is remarkable.
