Self-healing Asphalt Could Prevent Potholes and Save Costs on Vehicle Repairs | By embedding tiny plant spores filled with recycled oils into asphalt, scientists have created a material that can mend its own cracks.


Self-healing asphalt roads could soon offer a solution to the UK's pothole crisis, researchers say.

Designed with artificial intelligence from Google Cloud, a new type of asphalt made from biomass waste can mend its own cracks without the need for maintenance or human intervention. Scientists at Swansea University, King's College London and from Chile have found methods to "stitch" asphalt back together, hoping to create more durable and sustainable roads. Local road conditions in England and Wales were at an all-time low in 2024 due to "decades of underfunding", according to an annual survey by the Asphalt Industry Alliance.
