dc.description.abstract
This study investigates the development and application of asphalt rejuvenators derived from waste tyres through pyrolysis process. Two several products were produced and evaluated: an optimised Pyro-lytic Liquid Rejuvenator (PLR) and Biopolymeric Polynuclear Capsules (BPC) encapsulating PLR for self-healing asphalt mixtures. Rheological and self-healing properties of aged asphalt binders were examined using dynamic shear rheometer and tensile fracture-healing tests. The main results demonstrated that PLR significantly reduced the stiffness of aged binders, achieving properties comparable to unaged binders at 15% dosage by weight. BPCs enhanced self-healing, with a maximum Effective Healing Level (EHL) of 44.5% achieved at 1% dosage after 24 hours rest period at 20ºC. The results suggest that pyrolytic rejuvenators and encapsulated formulations provide effective and sustainable solutions for improving the durability of aged asphalt binders.
