The aim of this study was to perform a life cycle assessment (LCA) that quantifies the environmental impact and its uncertainty, associated with one center-lane mile of jointed plain concrete pavement (JPCP) road, designed by a pavement engineer using the Mechanistic-Empirical Design Guide (MEPDG). The scope consists of the initial construction and material impacts, as well as fuel loss due to pavement vehicle interaction (PVI), carbonation effects, lighting impacts, maintenance and rehabilitation requirements, and finally, disposal at the end of life. The impact assessment methodology used is IMPACT 2002+ which quantifies results using four categories: climate change, human health, ecosystem quality, and resources.The final result of the LCA is a probability distribution function for the impact of one-mile of concrete road. Using this methodology for a comparative LCA will allow one to comment on the significance of the difference between two pavements under consideration.
