Analysis and Comparison of Carbon Emissions of Different Asphalt Mixing Process

The thesis firstly defines the studying types of greenhouse gases. Then according to calculation method, we get the carbon emissions of common energies as calculation base. The thesis uses thermodynamic method to calculate the diesel consumption of HMA and WMA and gets the electricity cost according to literature, at last we use quota method to calculate the carbon emission. For asphalt recycling, we consider the total process including material production, transportation and mixing and calculate the carbon emissions with different RAP ratios. In conclusion, the WMA and recycling with certain RAP ratio reduce emission
