Conductive Compartmented Capsules Encapsulating a Bitumen Rejuvenator

This paper explores the potential use of conductive alginate capsules encapsulating a bitumen rejuvenator as new extrinsic self-healing asphalt method. The combine two existing technologies: (1) encapsulation and (2) induction heating to create system that will provide rapid effective pavement repair. work presents proof concept for process, which involves embedding into mortar mixture survival rate in mixture. A drip capsule production process was adopted scaled up 20l wet at 0.22 l/min. To prove effectiveness its ability survive were prepared subjected thermogravimetric analysis (TGA) uniaxial compression Test (UCT). test results demonstrated had suitable thermal characteristics mechanical strength mixing compaction process. Scanning electron microscopy (SEM) employed investigate physiological properties, such (oil) iron particle distribution, within capsules. electrical resistance tests proved capable conducting current. also tested their properties order determine whether they are distributing heat once heating. showed containing higher amounts (alginate/iron powder ratio 20:80 by weight) can efficiently conduct distribute heat. success an healing system, embedded mix. samples where then local damaging events, degree quantified. research findings indicate present promising approach development systems.
