(TU Delft Materials and Environment) Contributor Schlangen, E. (promotor) Liu, X. (copromotor) Degree granting institution Delft University of Technology Date 2020-11-23 Abstract Porous asphalt, due to its advantages of noise reduction and water drainage, is widely used in the surface layer of the highway in the Netherlands. However, the porous structure makes it prone to ravelling, therefore more frequent maintenance and reconstruction than other asphalt mixtures The porous asphalt service life can be extended with self-healing technology, such as: induction heating and encapsu-lated rejuvenator, but both methods have their limitations: induction heating be-comes less effective when bitumen oxidises, ages and loses its healing/recovery abil-ities, while encapsulated rejuvenator usually has a limited crack healing efficiency. Hence, this research aims to develop a unique self-healing system that combines two self-healing methods (induction healing and rejuvenator encapsulation), and the ad-vantages of the above two methods further extend the service life of the porous as-phalt. For this purpose, the development of the combined healing system was con-ducted in two research stages… Subject Self-healing asphaltCalcium alginate capsulesinduction heatingCombined healing system To reference this document use: https://doi.org/10.4233/uuid:d6b9b064-ae38-421e-a709-0fcc5a3f028f ISBN 978-94-6421-138-2 Part of collection Institutional Repository Document type doctoral thesis Rights © 2020 S.
