Essay by Eric Worrall
Apparently it’s the climate causing potholes, not slipshod, incompetent road maintenance, super heavy EVs, or people switching to large SUVs because of all the potholes.
Climate change is causing a pothole plague. Are robots and self-healing pavement the solution?
Mia Taylor 25th January 2024
Extreme heat waves, wildfires and flooding are among the most obvious impacts of the Earth’s changing climate.
But dire weather events are not the only way global warming is wreaking havoc worldwide. Climate change is also creating a pothole plague.
In 2023, there were nearly 630,000 reports of potholes in the UK, which marked a five-year high, according to data compiled by campaign groupRound Our Way. In the United States, meanwhile, about 44 million drivers reported damage to their vehicles from potholes in 2022, which was a massive 57% increase over 2021, according to AAA.
While ageing infrastructure and limited road maintenance budgets play a significant role in the problem, another culprit behind the marked proliferation of potholes is severe weather brought about by climate change, which is weakening roads.
“There are a number of issues caused by climate change that are impacting roads,” says Hassan Davani, Ph.D., an associate professor in San Diego State University’s Department of Civil, Construction, and Environmental Engineering. “Excessive heat can ultimately cause buckling of the roads, where additional thermal stress to the pavement materials can lead to cracks and potholes. We’re also experiencing more extreme flooding events, which causes a higher velocity of stream flow over the roads, resulting in more severe erosion of the pavement.”

Among the intriguing innovations emerging is the use of artificial intelligence (AI) and robots to address transportation infrastructure problems, including potholes.

Other commenters paint a slightly different picture of the situation;
Pothole politics is paralysing Britain
The nation suffers from executive dysfunction
…
Recently, though, we’ve gained a new unit of stupid political measurement: the pothole. Labour councils could have filled 24,000 potholes with the money they spent on diversity and inclusion in a year, according to a press release from CCHQ this week.
The briefing has an unmistakable whiff of election messaging. It came on the heels of a renewed pledge by Rishi Sunak to tackle Britain’s increasingly potholed and unpassable roads, and suggests the Tories are jockeying for position as the party of people who live in the material world, as opposed to those Marie Antoinettes of moral abstraction and virtue-signalling on the Opposition bench.
But can they pull this off? I’m not convinced. During a recent campaign visit to Darlington, in which he promised to address Britain’s pothole-ridden roads, Sunak pointed out a particularly large offender to the national media. But even after becoming, however briefly, Britain’s most famous bit of missing tarmac, it took another two weeks before anyone came along to fix it.

On balance I suggest government incompetence seems a more likely explanation than climate change. Perhaps if the government allocated more funds to fixing potholes, instead of blowing all their cash on green energy and white elephants like HS2, there might be fewer potholes.
Could robots help with road maintenance? Maybe – but given Britain’s dismal track record with government IT projects, I expect a robot road repair programme would be dogged by hilarious and excruciatingly inconvenient failures, like robots running off the road and filling holes in the wilderness, or filling all the drains because they mistook the drains for potholes. I imagine similar problems would occur with any government attempt to streamline resource allocation using AI technology.
In the meantime, my suggestion is if you haven’t already, consider purchasing a vehicle which can handle our degraded roads. Such vehicles are expensive to own in Britain, but repairing an axle broken by a degraded, poorly maintained road is also expensive. Such vehicles can also handle snow and ice much better than normal automobiles, when the government neglects to buy road salt for winter. If you install a bull bar, you are also much safer if you hit a large animal, like one of Britain’s out of control feral deer population. I’m not suggesting even a sturdy off-road vehicle would be guaranteed to survive a collision with a big buck, but driving a rugged vehicle has significantly reduced the risk of a feral animal encounter wrecking my vehicle or causing me injury.
Barely a day goes by I don’t encounter degraded road conditions which affirm my decision to purchase an off-road vehicle.

We don’t built roads with concrete here in Finland for the most part, not because of global warming, because cold weather destroys them rapidly.
Once there is any crack, that’s it, autumn comes it rains, then it freezes in the cracks and widens them.
As for Asphalt.
You can bet many smaller roads in the UK were made with the cheapest garbage mix. The material must also be consistent in its mix, if not, you get chunks breaking off from expansion and contraction, and uneven subsidence of the surface over time, where normal summer and winter cooling causes it to shatter.
Laying patches over potholes and wear actually accelerates the decline of the asphalt road, you need to replace it. Its of a different density than the old material, weight on that density differential causes it to break up more over time.
The flexibility of the material disappears over time as it dries out, its not different from an asphalt based roof. We bought a house in Lahti, the existing roof is Asphalt-like tiles, the roof is likely the same age as many of those asphalt smaller roads in the UK, 40 years. I have found 2 leaks this winter, because the material has hardened and dried out from very normal summers. I can peel off the bitumen over the nails they used on the tiles with my thumb nail, it flakes away. Then it contracts in winter, and when the melt comes, water gets in all those exposed little gaps in places, with a roof of that age.
Asphalt is cheaper and in the first part of its life, flexible, the downside is its longevity, whereas concrete has longevity (in warmer climates), but no flexibility for any subsidence or warming freezing
and is much more expensive to lay.

Hi Eric
Road damage is proportional to the 4th power of the axle weight. Therefore, BEVs cause three times the damage of ICE vehicles because they are more than 30% heavier.
Should we not tax BEVs more because they cause more damage?
Some great and worthy comments however no-one has mentioned the elephant in the room; increased heavy vehicles ever since the wide removal of rail lines. I know here in Sth Aust that loads of country lines have been closed with the subsequent increase in truck traffic. On the Eyre Peninsula the entire rail network has been removed and locals complain about the shocking state of the roads over there.
The other thing I note is in the late 90’s our pre amalgamation local council would grade the dirt roads a minimum of 4 times, and properly grade them too, not the skim they get now and now, since amalgamation, we’re lucky to a once a year skim that doesn’t fill pot holes or flatten corrugations.
Speaking of councils, how many are sending truck loads of rate payers money to the UN and is this why there’s no money and they are all in debt to the eyeballs?
