ATHENA The Athena Impact Estimator for Highways

The software provides environmental LCA results for Canadian regional materials manufacturing, roadway construction and maintenance life cycle stages. It allows custom roadway design, or users can draw from a library of 50 existing roadway designs. The software includes a large equipment and materials database and the flexibility to specify unique pavement systems – sub-base and base granular materials as well as hot and warm mix asphalt 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, if desired, to be included in the final LCA results. The software allows for quick and easy comparison of multiple design options over a range of expected roadway lifespans.
