Welsh scientists from Swansea University and King’s College London, in collaboration with Chilean researchers, have developed self-healing asphalt roads made from biomass waste and artificial intelligence (AI). The asphalt can mend its own cracks without maintenance or human intervention, addressing the UK’s £143.5 million annual pothole problem. The team used machine learning to study organic molecules in bitumen, the sticky black material in asphalt, and incorporated tiny plant spores filled with recycled oils that release when the asphalt cracks. In laboratory tests, the advanced asphalt material completely healed a microcrack in under an hour. The researchers aim to develop sustainable infrastructure by reducing carbon emissions from asphalt production and creating net-zero roads. The innovation has the potential to improve infrastructure and advance sustainability worldwide.
Researchers have created innovative AI-infused asphalt that automatically repairs cracks and damages, aiming to revolutionize the way urban infrastructure is maintained and alleviate the issue of potholes.
