高速公路预防养护技术减碳效果探究

Exploration of Carbon Reduction Effect of Expressway Preventive Maintenance Technology

在碳排放、碳中和的背景下,高速公路养护过程中的巨大碳排放已成为推进低碳目标的一大难点。相关研究表明,预防性养护能够有效降低高速公路养护全生命周期的碳排放,但其具体减碳效果未知。对此,采用基于定额的计算框架,结合相关工程定额文件及碳排放因子库,对不同预防养护技术的碳排放水平进行计算,并进行横向比较。通过构建案例,分析了不同预防养护技术的全生命周期碳减排效果,发现该场景下的微表处、稀浆封层这两类技术在减少碳排放方面表现优异。

In the context of carbon emissions and carbon neutrality,the enormous carbon emissions during highway maintenance have become a major challenge in promoting low-carbon goals.Related studies have shown that preventive maintenance can effectively reduce carbon emissions throughout the entire lifecycle of highway maintenance,but its specific carbon reduction effect is unknown.In this regard,a quota based calculation framework is adopted,combined with relevant engineering quota documents and carbon emission factor libraries,to calculate the carbon emission levels of different preventive maintenance technologies and conduct horizontal comparisons.By constructing a case study,the full lifecycle carbon reduction effects of different preventive maintenance technologies were analyzed,and it was found that the micro surface treatment and slurry sealing technologies in this scenario performed excellently in reducing carbon emissions.
