Potholes are more than an eyesore. Once they appear, they can grow quickly and create rough driving conditions, damage vehicles, and leave your driveway or parking lot looking neglected. Understanding what causes asphalt potholes can help property owners recognize problems early and take steps to protect their pavement.
How Do Potholes Form?
Water is one of the biggest contributors to pothole formation. Small cracks and openings in asphalt allow water to reach the layers beneath the pavement. When the underlying base becomes weakened, the asphalt above it can lose support.
Temperature changes can make the problem worse. During colder weather, water can freeze and expand inside pavement cracks. When temperatures rise and the ice melts, gaps can form beneath the surface. Repeated freezing and thawing can gradually weaken the pavement and create areas that eventually break apart under traffic.
Heavy or repeated vehicle traffic can also contribute to pavement deterioration, particularly when asphalt is already weakened by water or other damage.
Why Do Potholes Keep Getting Bigger?
A small pothole rarely stays small when it is left untreated. Traffic places repeated stress on the damaged area, causing more asphalt to break away. Additional water can then enter through the opening, accelerating the deterioration of the pavement below.
Prompt asphalt repair can help address potholes before surrounding pavement becomes more extensively damaged.
How Can You Help Prevent Potholes?
Regular pavement maintenance can reduce the conditions that contribute to pothole development. Property owners should address cracks before they become larger openings and watch for drainage problems or areas where water regularly collects.
Professional asphalt maintenance can also help identify developing pavement problems before they require more extensive work.
Sealcoating is another maintenance option that can help protect asphalt from moisture and other elements when applied at the appropriate stage of the pavement’s life.
When Should You Repair a Pothole?
If you notice a pothole developing in your driveway, parking lot, or other paved area, don’t wait for it to become a larger problem. A professional assessment can determine whether a localized repair is appropriate or whether the surrounding pavement needs additional attention.
