Recent advances on self-healing of bituminous materials by the action of encapsulated rejuvenators
Highlights Recent advances on encapsulated rejuvenators for asphalt self-healing were reported. Ageing, recovering and self-healing phenomena in bituminous materials were discussed. Different types and technologies of encapsulated rejuvenators were evaluated. Healing capability in bituminous materials by encapsulated rejuvenators was quantified. Advances to improve the future research in encapsulated rejuvenators were proposed.
Abstract Self-healing of bituminous materials represents nowadays a promising approach to increasing the lifespan of asphalt pavements. During the last decade, different techniques have been used by researchers to promote the self-healing capability of bituminous materials: crack-healing by externally triggered heating using magnetic field technologies, such as induction heating and microwave radiation, and, more recently, the use of embedded encapsulated rejuvenators to activate crack-healing through the recovery of the original properties of bitumen. During recent years, researchers have mainly focused their efforts on promoting the autonomic healing of bituminous materials by the action of encapsulated rejuvenating agents. This article presents an extensive and critical literature review of the processes of ageing, recovering and self-healing of bituminous materials, focusing on the use of rejuvenating agents to extend the life of pavements. Therefore, the different types and techniques to encapsulate rejuvenators, their evolution over the years, and their main applications in bituminous materials were analysed from a multiscale approach. Finally, based on the current trends in materials engineering, this article proposes advances and innovations to improve the future research in the field of encapsulated rejuvenators to promote asphalt self-healing, from a more sustainable point of view.
