Researchers develop self-healing asphalt that repairs cracks, stops potholes from forming
SMRTR summary
Researchers have developed a self-healing asphalt that repairs cracks using plant spore microcapsules filled with recycled oils. When cracks form, the capsules rupture, releasing oil to soften the bitumen and allow it to reconnect. Lab tests showed a microcrack healing in under an hour. This AI-assisted innovation aims to address the UK's pothole problem and could improve infrastructure globally, though it's still in development.
