Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Schlangen, E. (author)Self-healing asphalt, which is designed to achieve autonomic damage repair in asphalt pavement, offers a great life-extension prospect and therefore not only reduces pavement maintenance costs but also saves energy and reduces CO<sub>2</sub> emissions. The combined asphalt self-healing system, incorporating both encapsulated rejuvenator and...journal article 2021

Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Lin, P. (author), Zhang, Y. (author), Nahar, S. (author), Lommerts, B. J. (author), Schlangen, E. (author)Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack. When the microcrack encounters the capsule, the fracture energy at the tip opens the capsule and releases the...journal article 2021

Xu, S. (author), Liu, X. (author), Tabakovic, A. (author), Schlangen, E. (author)Self-healing asphalt, aimed to produce a sustainable asphalt pavement using green technology, has been studied in the past two decades. Technologies including encapsulated rejuvenator and induction heating have been proposed, demonstrated in the laboratory, and gradually evaluated in field application. This paper looks into the synergy effect...journal article 2020

Xu, S. (author), Tabakovic, A. (author), Liu, X. (author), Palin, D. (author), Schlangen, E. (author)It has been demonstrated that calcium alginate capsules can be used as an asphalt healing system by pre-placing rejuvenator (healing agent) into the asphalt mix and releasing the rejuvenator on demand (upon cracking). This healing mechanism relies on the properties of capsules which are determined by the capsule preparation process. In this...journal article 2019

Xu, S. (author), Liu, X. (author), Tabaković, Amir (author), Schlangen, E. (author)Improving the healing capacity of asphalt is proving to be an effective method to prolong the service life of an asphalt pavement. The calcium alginate capsules encapsulating rejuvenator have been developed and proved to provide successful localized crack healing in asphalt mastic. However, it is not known whether this self-healing asphalt...journal article 2019

Xu, S. (author), Tabakovic, A. (author), Schlangen, E. (author), Liu, X. (author)Researchers have demonstrated that the rejuvenator encapsulation method is a promising autonomic self-healing approach for asphalt pavements, where by the self-healing system improves the healing capacity of an asphalt pavement mix. However, potentially high environmental risk via leaching of hazardous chemicals such as melamine formaldehyde...journal article 2018

Xu, S. (author), García, Alvaro (author), Su, Junfeng (author), Liu, Q. (author), Tabakovic, A. (author), Schlangen, E. (author)In recent decades, researchers have revealed the great healing potential of asphalt and proposed various novel methods to inspire and improve the self-healing capacity of asphalt aimed to prolong the service life of asphalt pavement. In this review, up to date research progresses in induction healing and embedded rejuvenator encapsulation are...review 2018
