| 520 | 3 | |a Traditional road infrastructure maintenance involves significant monetary costs and environmental impacts. In this context, developing solutions to improve pavement durability is crucial. One promising solution is healing asphalt, which incorporates materials and technologies that allow the pavement to repair itself. This approach helps prevent and recover from cracks, reducing the need for frequent maintenance and repairs. As a result, it leads to lower resource consumption and reduced greenhouse gas emissions. This thesis proposes incorporating bio-oil capsules and conductive materials as additives into asphalt mixtures and experimentally evaluates their self-healing potential. Chapter 2 presents a review of the state of the art. The experimental methodology was structured to progressively increase the complexity of material interactions. First, Chapter 3 examines the effects of bio-oil incorporation into bitumen. Chapter 4 investigates the influence of both bio-oil and steel slag (a conductive material compared to traditional limestone) on mastic. Chapter 5 focuses on the production of calcium alginate capsules containing bio-oil. Finally, Chapter 6 presents the experimental evaluation of an asphalt mixture containing steel slag and bio-oil calcium alginate capsules. At the bitumen level, bio-oil modification demonstrated promising results by softening the binder and increasing penetration by 30% with just 1% bio-oil content, although complete healing was not achieved. At the mastic level, the combination of biooil and steel slag filler showed enhanced healing properties, with bio-oil counteracting aging effects while steel slag improved stiffness and resilience. However, at the asphalt mixture level, the healing techniques (encapsulated bio-oil and steel slag filler) did not significantly improve healing performance, as evidenced by similar dynamic modulus and phase angle values compared to the reference mixture. Overall, while the modifiers proved effective at nano (bitumen) and micro (mastic) levels, their limited success at the macro (mixture) level suggests that further research and methodological refinements may be needed to fully evaluate their potential in asphalt applications. | |
