Environmental impact assessment of induction-healed asphalt mixtures

Abstract

This paper demonstrates the sustainability of induction-healed asphalt mixtures (HEALROAD) by comparing the impacts this technology causes with those generated by asphalt mixtures maintained byconventional practices such as mill and overlay. The functional unit selected is a 1 km lane with ananalysis period of 30 years, and the stages considered are production, construction, maintenance,congestion, leaching and end-of-life. Two case studies have been analysed to evaluate the influence ofdifferent traffic strategies on the environmental impact of each maintenance alternative. Results showthe benefits of using the induction technology at hot points where traffic jams occur.
