Researchers have created self-healing asphalt that can mend its own cracks, reducing the need for frequent road maintenance and pothole repair. The material is made by embedding tiny plant spores filled with recycled oils into asphalt, which release their contents to soften the bitumen and allow it to flow back together when cracks form. In lab tests, the self-healing asphalt repaired microcracks in under an hour. This technology has the potential to extend the lifespan of roads by 30% and save countries billions of dollars in repair costs. The environmental benefits are also significant, as the material incorporates biomass waste and reduces reliance on petroleum-based products. However, more research is needed to determine its performance in real-life scenarios and potential structural stability issues. If successful, this technology could be scaled up for use on British roads within a few years, making roads more sustainable and reducing the impact of potholes on drivers and the environment.
Innovative self-healing asphalt technology has the potential to eradicate potholes and significantly reduce the financial burden of vehicle repairs on individuals and society.
