Home 5 Expertise center 5 Report 5 Athena Pavement LCA Tool

A free, web-enabled software application that provides environmental life cycle assessment (LCA) results for materials manufacturing, roadway construction and maintenance life cycle stages, allowing for quick and easy comparison of multiple design options over a range of expected roadways lifespans. The tool allows custom roadway design but also comes pre-populated with a library of editable roadway designs. It includes a large equipment and materials database and the flexibility to specify unique pavement systems and a host of user-specified concrete mix designs.   Users can also input use-phase operating energy and apply built-in pavement vehicle interaction algorithms to be included in the final LCA results. Recently a life cycle cost assessment (LCCA) modeling capability was integrated into the software allowing users to consider both cost and environmental burden together.
