Analysis on the carbon footprint of life cycle for typical steel bridge deck pavement system
摘要
Abstract
To quantify the carbon emissions of steel bridge deck pavement system,a process-based life cycle assessment method was applied to analyze the life cycle carbon footprint of steel bridge deck pavement system.A life cycle inventory database of carbon emissions for steel bridge deck pavement system was constructed through six processes:material production,construction,operation,maintenance,waste disposal and transporta-tion.The international roughness index was used to establish the carbon emission prediction model under the de-cay of traveling quality.SMUO simulation software for traffic delays simulation was used to establish the carbon emission model of traffic delays.A corresponding carbon footprint quantification framework and model was es-tablished,and a case study for typical bridge pavement system of lower EA(epoxy asphalt)+upper SMA(stone mastic asphalt)was implemented.The results show that the maintenance and operation phases contribute nearly 80％of the total carbon emissions,the additional carbon emissions caused by traffic delays amounts to about 24％of the total carbon emissions,while materials or construction processes such as curing agents and sandblasting rust removal contribute 8.11％and 5.42％of the total carbon emissions,respectively.关键词
