Asphalt is cheaper to install, and easier to repair, than cement concrete. But both require regular maintenance to ward off deterioration – including potholes. According to the Federal Highway Administration (FWHA), about 94 percent of all surfaces used for transportation – roads, streets, and highways – are paved with asphalt. The characteristics and properties of bitumen-based asphalt, also known as blacktop, are quite different than those of concrete, even if…

Why aren’t there any driveways in pictures of middle class homes from the 1890s? Because they didn’t have cars! The rest is history. Before anyone considers their next blacktop driveway repair project, it might help to consider the history of driveways themselves. As well as the old jokey question, “Why do we drive on parkways and park on driveways?” The answer to that question is simple: language evolves. The invention…

No driveway lasts forever. But just like with human health, the wellbeing of asphalt pavement depends on attentive maintenance: resealing, resurfacing, and ultimately repaving. New homeowners learn a hard lesson, gradually, as the home and its surroundings age and deteriorate. It depends on the components of the house, garage, driveway, and landscaping elements – especially the quality of materials and products – but with time a new roof, new paint,…

The 2021 US infrastructure bill leapt closer to becoming law in August with a strong vote of support from the Senate. So what might it mean for pothole repair? The obvious benefit of the $1.2 trillion Bipartisan Infrastructure Framework (a working title) is in how much will be dedicated to fixing roads and bridges. While a version of the bill has yet to be voted on in the House, and…

Potholes from freezing weather aren't the only thing that can go wrong with asphalt and concrete roads. The lessons from heat dome regions should be part of engineering, policy, and infrastructure planning. There are two misperceptions about road pavement that could be increasingly problematic in the years to come. They are: All asphalt is made the same (it’s not) The only threats to roads are the freeze-thaw cycles that cause…

The national ironman triathlon championship race is in Oklahoma this month. But just three months after harsh winter storms, literal potholes must be fixed. When cities host triathlons, marathons, criterions, and other mass outdoor athletic events, it’s a smart draw for those municipalities to welcome visitors. The athletes and their families and friends often spend a weekend – as well as their tourist dollars at hotels, restaurants, and local attractions.…

A bump in the road can be deadly to bikers, motorcyclists, scooter riders, and anyone in 2-wheeled vehicles. The need to fill potholes is greater than ever. The British magazine Cycling Weekly, in a concession to the poor quality of many roads in the UK, offered up an article in 2017 on how to bicycle safely in the presence of potholes. Among several techniques, one suggestion was to “bunnyhop,” a…

Where water flows to is where pavement is most likely to fail. So in areas where water stands still there may well be potholes lurking under the puddles. In the balance of life, there are bridges and there are underpasses. On the former a car will go up and over and the latter it’s down and through. Simple stuff, right? It also explains why, simply, there tend to be potholes…

Injurious falls occur more often outside the home than in. Artists in Chicago are filling potholes with bicycle parts – perhaps reducing pothole dangers. In this particularly cold and miserable winter of 2021, after the snow is sufficiently scraped or melted away from the streets of Chicago’s Rogers Park neighborhood, there are some filled-in potholes from late 2020 that should get more attention than road repairs typically do. That’s because…

It appears road maintenance, which should mean fixing small cracks before they become deadly potholes, will be prioritized.

Potholes cause costly damage to car wheels, suspension and steering systems. Tire blowouts are most common, but tougher new tire material offers better protection. Is there such a thing as a pothole-proof car tire? One Finnish company believes it can be done – so much so they are introducing a very resilient product in North America made of the same material as used in bulletproof vests. It comes with an…

Since the early 20th century, markings and reflectors have helped guide our way and keep us safe while driving. Too bad potholes don’t come with such warnings. While it’s commonplace today to see yellow and white lines, and different colored reflectors, embedded in our streets and highways, that hasn’t always been the case. The first painted lines down the middle of roads – in Wayne County, Michigan in 1911 –…
