Analysis of Carbon Emissions from Typical Construction Activities in Highway Reconstruction and Expansion Projects
The concept of green and low-carbon has become the main theme of highway reconstruction and expansion under the background of the"dual carbon"target.Earthwork and pavement are the main sources of carbon emissions during the construction period of highway reconstruction and expansion projects,which are also the key factors to reduce carbon emissions.The calculation method,carbon emission chain,facilities and scenarios were clarified in this article.The composition and proportion of carbon emissions from earthwork and pavement were analyzed through a"bottom-up"approach,which reveals the key factors that affecting carbon emissions,and the corresponding low-carbon measures were proposed.
