N2 - Incorporating extrinsic self-healing factors in road materials and pavements can transform the road construction and maintenance procebes by increasing their life span and eliminating or reducing the need for maintenance. One autonomic self-healing technology available for asphalt pavement is embedding in the material capsules containing rejuvenators. This work presents one production method for encapsulating rejuvenators and abebes capsules characteristics (physical and mechanical). Ca-alginate capsules with Bio-Oil as a rejuvenator were produced in different contents, changing the design parameters, namely the ratio of ca-alginate and rejuvenator. Capsules were characterized based on morphology, size, composition, thermal and mechanical strength.
