Research on Carbon Footprint Calculation of Low-carbon Highway Construction Technology Based on Life Cycle Assessment
In this paper, the life cycle carbon emission measurement method is adopted to calculate the carbon emission of the green construction technology used in Yanhuang Highway. The results show that: the carbon reduction rate of the upper structure of the bridge from steel bridge to precas tconcrete precast reaches 55.78％, the carbon reduction rate of the tunnel engineering optimized for cutting engineering reaches 44.66％, and the carbon reduction rate of arch skeleton slope protection optimized for CBS slope protection reaches 21.36％. Steel and concrete are the main sources of carbon emission of highway construction materials and the key control materials for carbon emission reduction. The carbon emission of raw materials should be reduced by optimizing design, improving construction technology or using similar replacement materials with low carbon emission. Small loaders and gouging machines are the main sources of carbon emissions in the mechanical equipment of precast concrete beam bridge, and 30 loaders are the main sources of carbon emissions in the slope protection construction of CBS.
