“…The inclusion of a rejuvenator into the asphalt mix via micro capsules to restore the original binder properties is a self-healing method studied by Su et al [64,67], Su and Schlangen [68] and García et al [69]. The principle behind this approach is that when micro cracks begin to form within the pavement system, they will encounter a capsule in the propagation path.…”

“…In conclusion, the optimum content of microcapsules in bitumen must comprise no more than 30% of overall bitumen volume within an asphalt mix needs to be less than 30% of bitumen volume in an asphalt mix [67]. More recently Su et al [64] demonstrated that rejuvenators produced from recycled waste cooking oil (WCO) can be encapsulated and used in the asphalt self-healing technology.…”

“…To date, only a limited number of self-healing mechanisms for asphalt pavements have been developed, such as the induction heating [16,48] and rejuvenator encapsulation [17,64,68]. To explore the additional potential of self-healing asphalt technology, new self-healing mechanisms must be developed to respond to broader range of performance demands, such as healing/rest time.…”

This paper explores the potential methods for evaluating a healing system for asphalt pavements. The healing system under investigation involves compartmented calcium-alginate fibres encapsulating an asphalt binder healing agent (rejuvenator). This system presents a novel method of incorporating rejuvenators into asphalt pavement mixtures. The compartmented fibres are used to distribute the rejuvenator throughout the pavement mixture, thereby overcoming some of the problems associated with alternate asphalt pavement healing methods, i.e., spherical capsules and hollow fibres. The asphalt healing efficiency methods to be evaluated in this paper include: (i) standard test methods for asphalt pavements, such as the Indirect Tensile Strength test and the 4 Point Bending Fatigue test; and (ii) alternative fracture tests such as the Semi Circular Bend test. The study employs fracture theory in order to evaluate the efficiency of the damage repair. The research findings demonstrate that including compartmented calcium-alginate fibres encapsulating a rejuvenator into an asphalt pavement mix does not significantly improve the healing properties of the asphalt pavement. Nevertheless, the findings indicate that, with further enhancement, compartmented calcium alginate fibres may present a promising new approach for the development of self-healing asphalt pavement systems. Additionally, the test results indicate that the 4 point bend fatigue test is the most suitable test for evaluating the performance of self healing asphalt pavements.
