This study quantifies energy consumption and carbon emissions across production stages for a new cold mix asphalt (New-CMA) using IPCC methods. Compared to hot mix asphalt, it achieves 48% lower total energy use and 40% lower carbon emissions, mainly from eliminating aggregate heating (97.6% and 93.6% reduction in mixture production). Suitable for low-to-medium traffic roads, it offers guidance for sustainable pavement practices.

📄 Abstract（原文）
Abstract Cold mix asphalt (CMA) offers promising potential for reducing the energy consumption and greenhouse gas (GHG) emissions associated with traditional hot mix asphalt (HMA). This study presents a comprehensive investigation of the energy consumption and carbon emissions associated with a newly developed CMA technology (New-CMA) incorporating a hydroxylated cycloalkane-based polymer additive, which improves workability at ambient temperatures. Energy consumption and carbon emissions were quantified across the whole production stages, using energy consumption method and emission factor method recommended by the Intergovernmental Panel on Climate Change (IPCC). The results demonstrate that the New-CMA achieves a 48% reduction in total energy consumption and a 40% reduction in carbon emissions compared to conventional HMA. Significant reductions were observed particularly in the mixture production stage, where energy use and carbon emissions decreased by 97.6% and 93.6%, respectively, due to the elimination of aggregate heating. Compared to traditional CMA, the New-CMA shows reductions of 9% in energy use and 10% in carbon emissions. These improvements are primarily attributed to the elimination of aggregate heating, lower mixing temperatures, and enhanced mixing efficiency. The technology is particularly suitable for preventive maintenance and structural layers in low-to-medium traffic roads. This study provides a comprehensive environmental evaluation and offers guidance for promoting sustainable pavement practices in urban construction.
