Scientists from the UK and Chile have developed a new type of asphalt that can repair its cracks over time. This innovation could significantly reduce the need for road repairs.
New Self-Healing Asphalt Technology
Researchers from King’s College London and Swansea University, in collaboration with scientists in Chile, have created self-healing asphalt inspired by the regenerative capabilities of trees. Made from biomass waste, this asphalt can heal microcracks in under an hour.
Utilizing Artificial Intelligence
The project is supported by Google's AI tools. Using machine learning and new data-driven models, scientists accelerated the research into bitumen oxidation, enhancing the self-healing potential of asphalt. An advanced data-driven model was developed to expedite atomistic simulations.
Potential Benefits and the Future
Self-healing asphalt may significantly extend the lifetime of roads, aligning with the UK's net-zero emission goals. Reducing repair needs could substantially cut infrastructure maintenance costs.
Current developments in self-healing asphalt offer a reliable and eco-friendly solution to infrastructure challenges. This will help build more sustainable roads and optimize maintenance costs in the long term.
