Abstract

This research aims to evaluate the potential environmental impact of epoxy-modified asphalt used as a pavement material for roadways in the Netherlands and identify what determines the environmental performance of the epoxy asphalt technology through life cycle assessment. Results indicated that the incor-poration of epoxy binder in asphalt could lead to significantly lower environmental impact than the unmodi-fied asphalt. Such benefits are attributed by the minimal maintenance interventions of a pavement with epoxy and their remarkably higher service life over the analysis period. Finally, although the initial price of epoxy-modified asphalt production and construction was substantially higher than of standard asphalt mixtures, the overall score of epoxy-modified asphalt pavement in all weight scenarios was lower than that of the reference structures reflecting the sustainability benefits of using this technology for roadway pavements.
