Researchers have developed a self-healing asphalt that can repair cracks without human intervention. The innovative material combines bio-based materials and artificial intelligence (AI) to extend the lifespan of road surfaces. The asphalt contains microscopic plant spores filled with recycled oils that are released when a crack appears, softening the asphalt and allowing spontaneous repair. In lab tests, the material was able to fill a micro-crack in under an hour, potentially increasing road longevity by 30%. AI was used to model the behavior of organic molecules in the asphalt, simulating oxidation and cracking processes to optimize the material’s composition. The technology also uses biomass waste, reducing dependence on petroleum resources and aligning with circular economy principles. The researchers estimate that the technology could be deployed on a large scale within a few years, providing a sustainable alternative to traditional repair methods and reducing carbon emissions associated with asphalt production.
