Research on Carbon Emission Assessment and Emission Reduction Plan for Urban Road Asphalt Pavement Maintenance
With the continuous improvement of road network in China,the proportion of roads requiring maintenance has been increased.A large amount of greenhouse gases and harmful dust are produced during the maintenance pro-cess.As the problems of resources and environment become increasingly prominent at home and abroad,the signifi-cant emissions have attracted widespread attentions.The carbon emission boundaries are studied and the carbon e-mission inventory is clarified.The carbon emissions from the production of raw materials,production of mixtures and construction stages are analyzed and calculated during asphalt pavement maintenance.The key links of carbon emis-sions are identified;According to the links,targeted emission reduction measures are proposed from the perspective of road design,along with an analysis of emission reductions and engineering costs,providing reference for emission reduction in road maintenance projects.
