Description

technical field [0001] The invention relates to the field of carbon emissions in road engineering construction, in particular to an evaluation method for carbon emissions in asphalt surface layer construction. Background technique [0002] Asphalt pavement is the main pavement form of high-grade highways in my country and one of the most important large-scale infrastructures. The machinery required for raw material production, mixing, transportation, paving and rolling during asphalt pavement construction consumes a lot of fuel consumption and electricity, and emits a lot of CO 2 and other greenhouse gases. The high energy consumption and carbon emissions of asphalt pavement construction have attracted increasing attention, and low-carbon construction technology has become a research hotspot. However, due to the lack of a comprehensive quantitative analysis of carbon emissions in asphalt pavement construction, the development and application of low-carbon construction tech...
