【 摘 要 】

Over the past few decades, the growing interest in pavement sustainability has led researchers in government agencies, industries, and academia to develop various sustainability rating systems and life-cycle assessment (LCA) tools for roadways and pavements. However, many of the existing pavement LCA tools use outdated databases and, at present, there are no regional LCA tools available. This study focuses on regionalizing the pavement LCA by collecting and analyzing local data from the state of Illinois. This study attempted to develop a life-cycle inventory (LCI) database. In addition, an inventory analysis for various pavement materials, based on the ISO 14044 guidelines, was performed. As such, the greenhouse gas (GHG) emissions and energy consumption per unit mass of materials were computed and combined to develop a regional LCI database. The study updated the existing vehicle emission factors through simulations using EPA’s newest vehicle emission simulator, MOVES. As a result, accurate emission factors for six various types of mobile vehicles were computed and presented.
