It is only natural to want to fix potholes as soon as possible. Potholes can cause accidents and damage to vehicles. In addition, small potholes can get worse if they are not addressed quickly. But while you can perform emergency repairs at any time, permanent repairs should wait for warmer weather conditions. Our experts on asphalt paving in Lodi, CA, offer these three reasons for repairing potholes in the Spring.
Temperature is critical when it comes to laying asphalt. Hot mix asphalt is stored in a well-mixed liquid state inside of a heated truck. When the weather is warm, it will remain in its liquid form long enough to pour it out, spread it, and level it off. It will then harden gradually to form a durable surface with a tight seal. On the other hand, asphalt begins to cool and thicken as soon as it leaves the truck during cold weather. This thickening can lead to uneven pouring or cause the asphalt to harden before spreading and leveling.
It's also important to note that frozen ground can cause the embedded aggregates to loosen and break free. This makes it more likely for a pothole patch not to be tight, which could allow room for water intrusion or lead to a new pothole in the very same spot.
Wet weather is relatively common during the Spring, but snow and heavy rain are rare. You can easily do asphalt repairs during a drizzle without any damaging effects. However, heavy precipitation can cause asphalt to cool too quickly or lead to water build-up within the deeper layers of the new surface. Spring is the ideal time for repairs since most rains are usually brief and light.
Winter weather can take a toll on asphalt surfaces. Asphalt tends to expand and contract during cycles of thawing and freezing or significant snowfall. Accumulation can further weaken the structure of the asphalt. Water intrusion and cracking are pervasive, and if your asphalt has developed a pothole, there are likely other areas that are less severely damaged that you have not noticed. Waiting until Spring for pothole repairs allows you to fully assess the rest of the asphalt for holes or cracks that you should address. Cold patch asphalt is a great short-term fix for potholes because it is applied directly from the container without the need for heating. However, it is not generally best to use as a long-term solution. It's important to remember that if you used a cold patch to get you through the winter season, Spring is a perfect time to replace it with durable hot mix asphalt designed to last.
