This paper reviews how road construction impacts the environment and how to measure it using life cycle assessment (LCA). They found that different stages of making a road, like building materials and energy use, affect things like climate change, acidification, and more. Not all methods can measure all impacts, and the results vary based on what materials and energy are used. Different databases exist for assessing the life cycle of road pavements, but most studies agree on the steps involved. The research offers guidance on choosing the right method to assess environmental impacts.
