Prediction model for energy consumption and carbon emission of asphalt surface construction

Abstract

The construction of asphalt surface layer will generate a lot of energy consumption and carbon emissions. In order to realize the energy-saving and low-carbon construction of asphalt pavement, it is of positive significance to establish a calculation model for energy consumption and carbon emission of asphalt surface layer construction. This paper uses the LCA method to establish a calculation model for estimating the energy consumption and carbon emission of asphalt surface layer construction through data query and construction site analysis. It uses the example calculation to analyze the key links of construction energy consumption and carbon emission and proposes effective Low carbon construction technology. The results show that the three processes of mixture transportation, asphalt de-barrel heating, aggregate drying and heating are the key links in the whole asphalt surface construction process. Warm mix construction technology and control of aggregate moisture content technology can effectively reduce construction energy consumption and carbon emissions.
