高架快速路沥青铺装不同养护方案碳排放核算分析

Carbon Emission Analysis of Various Maintenance Schemes for Asphalt Bridge Deck Pavement on Elevated Expressway

在“碳达峰、碳中和”目标要求下,明晰快速路沥青铺装不同养护方案的碳排放强度,进而提出减碳技术路径和方案。以上海市某高架快速路养护为例,基于LCA和定额法,核算了不同养护方案的碳排放值,旨在探索不同养护方案的碳排放强度差异及其减碳方向,为高架快速路低碳养护发展提供技术支持。

In line with the national strategic goal of carbon peak and carbon neutrality,it is imperative to clarify the carbon emissions associated with various maintenance schemes for asphalt pavement on elevated expressways.Furthermore,this analysis aims to propose carbon reduction technology strategies and plans.Using a specific elevated expressway in Shanghai as a case study,the carbon emissions of different maintenance schemes will be calculated using Life Cycle Assessment(LCA)and quota methods.The objective is to explore the variations in carbon emission intensity and identify directions for carbon reduction within different maintenance schemes.Ultimately,this study will provide essential technical support for the development of low-carbon maintenance practices for elevated expressways.
