Evaluation of sustainable use of RAP from LCA perspective: a literature review

Transport infrastructures have an important social and economic role, but also a large environmental impact. As infrastructure requires large amounts of material, infrastructure sustainability has focused on materials and technologies including all phases from design to rehabilitation. In that direction there are a lot of Life Cycle Assessment (LCA) studies conducted on mixtures with different Reclaimed Asphalt Pavement (RAP) content. Using RAP into new mixtures provides advantages from both environmental and economic point of view. The aim of this work is to review previous LCA studies related to an environmentally sustainable use of RAP in mixtures.
