“双碳”目标下的沥青路面减碳技术发展研究综述

A Review on Research of the Carbon Reduction Technology of Asphalt Pavement

道路工程的碳排放不仅仅存在于道路基础设施建设期,从生命周期评价的角度来看,长期的运营维护施工碳排放占比高达80%。因此,在道路基础设施领域开展节能减排技术的研究和应用对于实现“双碳”目标具有重要意义。本文总结了为实现道路建设的节能减排进行的工作。首先,要建立科学、有效的碳排放评价体系;其次,总结了目前在材料、结构、养护等方面降低碳排放的研究进展;最后,对道路建设今后的节能减排技术发展方向和趋势进行了分析。分析结果表明,新型的材料和科学的养护技术在节能减排中发挥着重要作用,应在今后的发展过程中加强技术创新研发和成熟技术的推广应用。

The carbon emissions of road building is not only from the construction period,from perspective of life cycle assessment(LCA),the carbon emissions proportion of long-term operation and maintenance stage is as high as 80%.Therefore,carrying out the research and application of energy conservation and emissions reduction technology in the field of road infrastructure is important to realize the goal of“double carbon”.This paper summarized the work that scholars did to realize the energy conservation and emissions reduction of road construction.At first,we need to establish a scientific and effective evaluation system of carbon emissions.Secondly,the progresses in the study on materials,structure and maintenance of reducing carbon emission were reviewed.Finally,this paper analysed the way forward and trend of road construction and maintenance technology.Analysis results show that the new materials and the scientific conservation technology play an important role in energy conservation and emission reduction.In future studies,we should enhance the technology innovation and the promotion and application of mature technology.
