A runway reconstruction project at John F. Kennedy airport was recently completed, and with the help of the Port Authority of New York and New Jersey (PANYNJ) the goal for the case study was defined to perform a standalone/benchmark study to quantify the environmental impacts from the life cycle stages (materials stage and construction stage) of the different layers of the erosion and shoulder pavements. Several runway reconstruction project-related documents were shared by PANYNJ from which data and information relevant to the case study were extracted. Environmental impacts that are considered and reported include primary energy (spilt by consumed and used as a material), greenhouse gas emissions, particulate matter, and ozone depletion. The shoulder pavement had a higher set of environmental impact contributions than the erosion pavement due to the difference in pavement thicknesses. Among materials stage, construction stage, and transportation, the materials stage had the highest environmental impacts followed by the transportation of materials.
