Self-Healing Roads:  Turning Cooking Oil into Pothole Patching

Potholes cost Britain £14.4 billion annually. Engineers are exploring a solution: self-healing roads. Research suggests adding recycled cooking oil to asphalt significantly increases its durability. Water seeping into cracks during winter, freezing and expanding, is the main culprit in pothole formation. This research, involving Google and King’s College London, used a sophisticated computer model to study the process at a molecular level, aiming for more effective road maintenance.
