基于LCA的公路路面建设碳排放量测算探究

Carbon Emission Calculation of Highway Pavement Construction Based on LCA

针对公路路面建设碳排放量问题,基于LCA理论,明确公路路面生命周期评价范围,并以西藏拉萨境内某旅游环线公路路面建设为案例,分析、核算路面建设生命周期内碳排放量占比、各建设阶段碳排放量影响因子占比,认为建设过程中减少运距、改善材料生产工艺可以达到降碳减排的目的.

Aiming at the problem of carbon emissions in road pavement construction,the life cycle assessment scope of road pavement is defined based on LCA theory.Taking a road pavement construction in Lhasa,Tibet as a case,the proportion of carbon emissions in the road pavement construction life cycle and the proportion of influencing factors of carbon emissions in each construction stage are analyzed and calculated.It is suggested that reducing the transportation distance and improving the material production process can achieve the purpose of reducing carbon emissions.
