Self-healing asphalt uses plant spores to stop potholes before they start

Scientists in the UK have developed a self-healing asphalt using biomass waste and artificial intelligence. This innovative material can autonomously repair cracks within an hour, potentially solving the UK's £143.5 million annual pothole problem. The asphalt contains microscopic plant-derived spores filled with recycled oils that release when cracks appear, "stitching" the surface back together. This breakthrough could extend road lifespan, reduce maintenance costs, and lower carbon emissions from road repairs, contributing to the UK's 2050 net-zero goal.
