Potholes in Asphalt Streets and Driveways: What Causes Them?

what causes potholes?

Potholes are a problem that cities and homeowners across the country have experienced on both streets and driveways. Pothole repair is something that municipalities budget money toward every year, and it seems like potholes develop even on paved streets that don’t have much traffic. What causes potholes, exactly?

How Potholes Are Formed

New potholes usually start to show up on streets right around the start of springtime. How potholes are formed has a lot to do with weather and how roads are constructed.

Most streets are layered, with the bottom layer consisting of gravel and packed dirt to allow snow and rain to drain properly. The bottom layers of a street are usually covered with asphalt, which is able to repel water and re-direct it to the side of the road or into drains. But asphalt repairs are a consistent requirement for every city, since weather and traffic put a constant strain on streets.

Potholes are caused by a constant hot-cold-hot-cold temperature change and regular stress on asphalt streets from traffic flow. These combine to create small cracks in the asphalt, which lets dirt and water from rain and snow to get into the gravel and dirt underneath.

This water then freezes, and we all know what happens to water when it’s frozen: it expands. The expanding ice leaves a hole when it melts, and the asphalt overhead collapses into the hole (which is made worse by continued traffic).

All of these factors combined can leave a road with many potholes that will only continue to get worse with time.

How to prevent potholes from forming

It’s important to know how to prevent potholes from forming, or else you’ll be stuck with a costly problem. Here are various ways you can keep your driveway or road pothole-free:

  • Seal cracks – When a crack begins to form, seal it off while you can. Once the weather turns from rain to freezing temperatures, a small crack can lead to a pothole and ongoing issues.
  • Maintain road drainage – Stopping water from pooling in a street is key to preventing potholes. Keep street gutters clear from debris so water can drain properly.
  • Resurface your pavement regularly – Resurfacing your road will protect it from water and moisture getting into any cracks. This will not only make your asphalt surface look brand new, but you will feel confident that potholes won’t be forming anytime soon.

  • When filling a pothole, make sure it is fully compacted and filled to the top of the hole
  • Smooth the surface of the pothole by using a hand tamper roller or a plate compacter

What are the dangers of potholes?

Potholes can create a dangerous situation for anyone on the road. Potholes increase the likelihood of the following:

  • Damage to car tires, shock absorbers, steering components, exhaust systems, and more
  • Car repairs with high costs
  • Accidents with other cars
