Asphalt pavement is durable, but over time, it can develop cracks and potholes due to wear and tear, weather conditions, and heavy traffic. Addressing these issues promptly can extend the life of your pavement and prevent costly repairs. Two common repair methods are crack sealing and pothole patching. While both serve to maintain pavement integrity, they address different problems and require distinct approaches. We at Andersen Asphalt & Striping would like the opportunity to explore the differences between crack sealing and pothole patching and when to use each method.
What is Crack Sealing?
Crack sealing is a preventative maintenance technique used to repair cracks in asphalt pavement before they expand and cause significant damage. It involves filling cracks with a specialized sealant to prevent water and debris from penetrating the asphalt surface. This method is typically used for cracks that are narrow but deep, usually between 1/4 inch and 1 inch in width.
Benefits of Crack Sealing
Prevents Water Damage: Water can seep into cracks, weakening the base layer and leading to potholes.
Extends Pavement Life: Proper sealing can add years to the life of an asphalt surface.
Cost-Effective Maintenance: Regular crack sealing reduces the need for expensive repairs or resurfacing.
Improves Safety: Sealing cracks minimizes trip hazards and creates a smoother driving surface.
What is Pothole Patching?
Pothole patching is a reactive repair method that addresses potholes that have already formed. Potholes occur when cracks or weak spots in the asphalt allow water to penetrate, leading to base layer erosion and surface collapse. Patching involves filling these holes with new asphalt material to restore the pavement’s smoothness and integrity.
Benefits of Pothole Patching
Restores Structural Integrity: Filling potholes prevents further deterioration of the pavement.
Enhances Safety: Potholes pose a significant hazard to drivers, cyclists, and pedestrians; patching reduces the risk of accidents.
Prevents Further Damage: Unrepaired potholes can expand and lead to more extensive pavement failures.
Quick and Efficient: Depending on the method used, pothole patching can be a fast repair solution.
When to Use Each Method
1) Use crack sealing for early-stage pavement damage when you notice small cracks developing. This is a cost-effective way to extend the life of your asphalt.
2) Use pothole patching when cracks have progressed into potholes. At this stage, sealing is no longer effective, and immediate repair is required to prevent further pavement degradation.

Ultimately, both crack sealing and pothole patching play vital roles in asphalt maintenance. Crack sealing is a proactive measure that helps prevent pavement failures, while pothole patching is a necessary reactive solution for already-damaged surfaces. Implementing a regular pavement maintenance plan that includes both methods can help keep roads, driveways, and parking lots in top condition for years to come. If you’re unsure which method is right for your pavement, consult a professional asphalt contractor to assess your needs and recommend the best solution.
