浅析路面大中修工程碳排放和碳减排措施

Brief Analysis of Carbon Emission and Carbon Emission Reduction Measures for Pavement Overhaul and Middle Repair Engineering

摘要:

为完善路面大中修工程设计决策方法体系，对路面大中修工程的碳排放计算和碳减排措施进行研究。以本地区路面大中修工程实践为例，针对现场路况和调查结果，在前期设计中提出3种路面维修方案，并进行比选增加了碳排放方面的对比分析。首先，确定以旧路翻挖外运、新料生产拌和、现场摊铺施工为碳排放计算范围，其次采用排放因子法针对不同设计方案的碳排放进行计算和汇总，对比各方案碳排放总量和上、下沥青面层各分层的碳排放，最后结合各阶段碳排放的占比情况，提出碳减排措施建议。

Abstract:

In order to improve the decision-making system for the design of pavement overhaul and middle repair engineering, the carbon emission calculation and carbon emission reduction measures of pavement overhaul and middle repair engineering are studied. Taking the practice of overhaul and middle repair engineering in the region as an example, aiming at the on-site road conditions and investigation results, three pavement maintenance schemes are proposed and compared in the earlier stage of design. And the comparative analysis of carbon emissions is added. Firstly, the calculation range of carbon emissions is determined according to the excavation and transportation of old roads, production and mixing of new materials, and on-site paving construction. Then, the emission factor method is used to calculate and summarize the carbon emissions of different design schemes. The total carbon emissions of each scheme and the carbon emissions of each layer of the upper and lower asphalt pavements are compared. And finally, combined with the proportion of carbon emission in each stage, the carbon reduction measures are put forward.
