Method for evaluating carbon emission in asphalt surface course construction

Abstract

The invention discloses a method for evaluating carbon emission in asphalt surface course construction. According to the method, the carbon emission in the asphalt surface course construction is divided into 8 units of site stockpiling, aggregate loading, aggregate heating, asphalt heating, asphalt mixture mixing, transportation, paving and grinding according to different unit processes of the asphalt surface course construction, and a carbon emission source is defined into energy consumption carbon emission generated by using of mechanical equipment and a transport cart, and carbon emission of asphalt and asphalt mixtures under a high-temperature state. According to the method, corresponding asphalt surface course construction carbon emission calculation formulas are established according to different construction units and carbon sources under the historical background of energy conservation and emission reduction as well as low carbon and environment protection, the carbon emission loads are graded, and an asphalt surface course carbon emission evaluation method is established on above basis, so that a research direction is indicated for the change, from a high carbon emission mode to a low carbon emission mode, of the later asphalt surface course construction process, and great significance is brought to remit the greenhouse effect and propel the research process of low-carbon type roads.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and in particular relates to an evaluation method for carbon emission of asphalt surface layer construction. Background technique [0002] As the harm caused by global warming becomes more and more serious, people gradually realize that it is urgent to control the emission of greenhouse gases, and CO 2 、CH 4 , N 2 As the main component of greenhouse gases, O is the key research object of energy conservation and emission reduction, because CO 2 It accounts for the largest proportion of greenhouse gases, about 60%. Therefore, the term carbon emissions is commonly used as a general term for greenhouse gases. When calculating carbon emissions, other greenhouse gases are converted into equivalent CO 2 , in order to calculate the total amount of greenhouse gas emissions, and then judge the intensity of the greenhouse effect. [0003] The road transportation industry is ...

AI Technical Summary

Problems solved by technology

[0004] Some studies on carbon emissions from asphalt pavement construction have been conducted at home and abroad, but there are two deficiencies in the research process: First, the research on carbon emissions from asphalt pavement construction is mainly based on energy, and the research on high-temperature emissions of asphalt mixtures has not yet started. The quantitative calculation of emissions is still in the exploratory stage; second, my country lacks a systematic carbon emission evaluation method for asphalt pavement construction, and the evaluation indicators and grading standards cannot be clarified, resulting in the lack of necessary theoretical basis for the development and application of low-carbon technologies, and no obvious pertinence , which is not conducive to the construction of low-carbon and environmentally friendly asphalt pavement
