#potholes

Remember all those potholes I reported to the city? Well, I think they've all been filled, and I get notified for each one! They update the issue with a before & after shot which is pretty awesome.

As I went down the streets around my house this evening seeing all the holes filled was great. Easier and safer to bike on and drive on now!

Sir Rod Stewart is right - I was in South #Essex myself a week ago, having turned off the #A12 on a fruitless search for a loo (I later found one at #Chelmsford), and regularly found myself having to drive almost in the crown of the road to avoid #potholes , and this is in a modest #VW #Polo (stock springs, not lowered or anything like that) - not a #Ferrari (I dread to think how much that would cost if you scraped it, even a millionaire may baulk at the garage bill)

Could AI fix the country’s pothole problem?

Self-healing asphalt roads, made from biomass waste and designed with the help of artificial intelligence (AI), could offer a promising solution to the UK’s pothole problem, which is estimated to cost £143.5 million a year.

Researchers from Swansea University and King’s College London, in collaboration with scientists in Chile, have developed a new type of asphalt that can repair its own cracks over time, eliminating the need for manual road maintenance – offering a promising solution to the UK’s pothole problem.

This research has been accelerated by AI and machine learning with support from Google Cloud. This work has been used to discover chemical properties and eventually create virtual molecules to serve a specific purpose, as with drug discovery.

While still under development, researchers say self-healing asphalt holds immense promise for improving infrastructure and promoting sustainability worldwide. Researchers say this innovation aligns with the UK government’s net-zero emissions goals and addresses the significant financial burden of road maintenance.

Potholes and cracks form when bitumen—the sticky black material in the asphalt mixture—hardens through oxidisation, but the exact processes behind this are not entirely known.

The team has found a way to reverse cracking and develop methods to “stitch” asphalt back together, creating more durable and sustainable roads.

During the research, a type of AI known as machine learning was used to study organic molecules in complex fluids like bitumen. The team developed a new data-driven model to accelerate atomistic simulations, advancing research into bitumen oxidation and crack formation. They are also collaborating with Google Cloud to simulate the behaviour of the bitumen on a computer.

To make the asphalt “self-healing”, the team incorporated tiny, porous materials known as spores, which are smaller than a strand of hair and produced by plants. These spores are filled with recycled oils, which are released when the asphalt begins to crack, helping to reverse the process.

In laboratory experiments, this advanced asphalt material was shown to completely heal a microcrack on its surface in less than an hour.

Dr Jose Norambuena-Contreras, a Senior Lecturer in the Department of Civil Engineering at Swansea University and an expert in self-healing asphalt, said: “As part of our interdisciplinary study, we have brought together experts in civil engineering, chemistry, and computer science, combining this knowledge with the state-of-the-art AI tools of Google Cloud.

“We are proud to be advancing the development of self-healing asphalt using biomass waste and artificial intelligence. This approach positions our research at the forefront of sustainable infrastructure innovation, contributing to the development of net-zero roads with enhanced durability.”

A substantial portion of carbon emissions from roads is linked to asphalt production. As the highway sector increasingly prioritises carbon reduction to support the UK Government’s goal of achieving net-zero emissions by 2050, advancing innovative bituminous materials for asphalt roads has become a key research priority.

Dr Norambuena-Contreras said: “To transition to more sustainable net-zero asphalt roads, the UK Government and private sector must invest in initiatives that drive innovation. Achieving this vision by 2050 will only be possible through the united efforts of academia, government, and industry.”

While still in development, the team’s research has enormous potential to improve infrastructure and advance sustainability around the world.

Dr Francisco Martin-Martinez, an expert in computational chemistry at King’s College London, said: “In our research, we want to mimic the healing properties observed in nature. For example, when a tree or animal is cut, their wounds naturally heal over time, using their own biology. Creating asphalt that can heal itself will increase the durability of roads and reduce the need for people to fill in potholes.

“We are also using sustainable materials in our new asphalt, including biomass waste. This will reduce our dependence on petroleum and natural resources. Biomass waste is available locally and everywhere, and it is cheap. Producing infrastructure materials from local resources like waste reduces the dependence on petroleum availability, which helps those areas of the world that have limited access to petroleum-based asphalt.”

Iain Burgess, UKI Public Sector Leader at Google Cloud, added: “We first worked with Dr Francisco Martin-Martinez when he joined the Google Cloud Research Innovators Programme in 2022, providing him access to Google experts, technical resources and training to support his research. Now, it is inspiring to see how teams at Swansea and King’s College London are unlocking the power of cloud-based and AI tools, including Gemini and Vertex AI, to drive more efficient processes and discover chemical properties.”

Good Morning #Canada
My fake holiday calendar says it's National Pothole Day, which seems a couple of months early Canada. The average large Canadian city will fill 175K to 200K #Potholes each year, and vehicle owners will suffer $Billions in damage driving over them. Climate change is extending Pothole season and driving innovation to reduce the problem, including the application of (shudder) "AI". I may eventually be outsmarted by a chunk of asphalt.

CBCHate those pesky potholes? You won't like what's coming with climate change | CBC NewsPotholes cost Canadians $3 billion in vehicle repairs each year, and without action, climate change will only make that worse. Fortunately, engineers have been working to develop better, longer-lasting and more sustainable materials, with innovations like self-healing asphalt and AI-backed roads. 

Here some pothole natural history for you, right on time for Simeon Brown's announcement of a $4 billion(!) fund to fix NZ potholes.

This hedgehog was squashed onto Leadleys Road, between Ōtautahi-Christchurch and Lincoln, on 18 December 2023. Its spines and tough skin got it pressed into the road by passing cars. This carcass finally dislodged yesterday, taking part of the road with it. The divot will now get opened into a pothole.
