Title: Environmental Impact of Concrete Pavement Construction Based on Life Cycle Assessment
Accession Number: 01515328
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: To evaluate the environmental impact of the concrete pavement based on life cycle assessment, this study focuses on the following three stages of pavement construction life: raw material and cement production, material transportation and surfacing. Six main environmental indicators are considered, including abiotic depletion potential (ADP), global warming potential (GWP), photochemical (POCP), acidification (AP), eutrophication (NP) and human toxic (HT). The results show that the stage of raw material and cement production has the largest impact on the environment, which is responsible for 71.18% of the total impact. The impact of the material transportation accounts for 27.81% of the total. The stage of surfacing has minimal environmental impact, which accounts for 5.4%. After characterization, normalization and weighting of all environmental impact indicators, concrete pavement shows largest impact on ADP and GWP, which account for 65.11% and 25.00% of the total impact, respectively. Among them, most of the impacts derive from the cement production. Therefore, optimizing the cement production process is an effective way to accelerate the sustainable development of road and transportation system, which also demonstrates the necessity of the current national strategy to develop energy efficient cement plant.
