Vila-Cortavitarte, Marta (author), Jato-Espino, Daniel (author), Tabakovic, A. (author), Castro-Fresno, Daniel (author)Self-healing within asphalt pavements is the process whereby road cracks can be repaired automatically when thermal and mechanical conditions are met. To accelerate and improve this healing process, metal particles are added to asphalt mixtures. However, this approach is costly both in economic and environmental terms due to the use of virgin...journal article 2019
